Transcript: X-Ray X-Ray is an electromagnetic wave of high energy and very short wavelength, which is able to pass through many materials that are impenetrable to light. Introduction General Information X-rays are electromagnetic waves with wavelengths in the range of 0.01 to 10 nanometers General Information there are two types of x-rays - soft and hard soft- soft X-rays are easily absorbed in air hard- X-rays are widely used to image the inside of objects X-rays were discovered by accident by German scientist Wilhelm Conrad Roentgen they can penetrate less dense matter such as skin and body tissue X-Ray Wavelength Real World Real World Applications X-Rays are used in hospitals and the medicial field to produce photographs of bones that have been broken X-Rays are created in machines by passing a current between two electrodes in an evacuated tube. As the electrons hit the positive electrode, an X-Ray is created. Future X-Rays X-Rays and Space Travel? X-Rays of the Future Celestial bodies such as stars, pulsars, and even black holes give off X-Ray waves. NASA scientists are trying to use only X-rays to be able to locate themselves in space.

Transcript: By: Foluke Akinkunmi, Jalen Griffin , Erin Barrington David Wade & Ryan Brockway X-RAYS Electromagnetic Spectrum X-rays are a form of electromagnetic radiation. They belong to the short- wave lenght, high- frequency end of the electromagnetic spectrum, between the gamma and the ultraviolet radiation. Key Characteristics Wavelenght of x-ray: from 0.01 to 10 nanometers Frequency of x-ray: from 30 petahertz to 30 exahertz Energy of x-ray: from 100 eV to 100 keV Key Characteristics X-Rays in everyday use The main use for x-rays are for medical imaging. Doctors often use this to look at things like fractures and brain tumors. The other use is to explore the cosmos and even treat cancer. Another use is the baggage scanner at the airport. They use this to see through your bags to check for dangerous or harmful content. X-rays are used in industries to inspect various types of materials to see if they are acceptable. X-rays bounce off of bones and exsposes cancer or growths to docotrs so they can treat it. This also applies for broken bones. X-rays penetrate easily through some materials like as fat and m A lot of people worry that x-rays are harmful. However, they are not. It can be if you're exsposed for too long. It can mutate your cells and that may lead to cancer. The tissue or organ will depend on the aamount of radiation you are exsposed to. It is helpful in the sense that it helps you see what and where is injured, so you can get help and heal better and faster. How safe are X-rays? How safe are X-rays?

Transcript: X-Ray's Imagine being in a car, in the passenger seat. And all of the sudden out of nowhere, your car is struck by another, your body flails all over the place like your a crash dummy, and you are so dumbfounded by what just happen you can barely even remember it. An ambulance brings you to the hospital to see what could possibly be wrong, you arrive at the hospital and are immediately scanned by an x-ray, and 10 minutes later you find out that your arm is broken. Background Info Intro + X-rays are a quick and painless ray that have many different functions in our daily lives, they can do anything from diagnosing cancer to treating that cancer. X-rays have opened up many different opportunities for America by letting doctors precisely detect injuries in their patients, aiding in the development of CT scans which help doctors to diagnose diseases, and finally by detecting fail points/flaws inside of structures and metals. All About X-Rays About Who Wilhelm Conrad Rontgen was a German mechanical engineer and physicist, who in November 1895, discovered electromagnetic radiation in a wavelength range known as X-rays or as some may know it, Roentgen rays. Wilhelm Conrad Röntgen Wilhelm's first ever x-ray was of his wife's hand This was an achievement that gifted him with the first Nobel Prize in Physics in 1901 as he was the first person to discover electromagnetic radiation in a wavelength range, which are known to us as X-rays today. Although, many people had observed the effects of X-ray beams before, Wilhelm Roentgen was the first one to study them systematically and as many may say, "crack the code." Wilhelm Conrad Röntgen What X-rays are one of the seven high-energy forms of electromagnetic radiation. And these various forms of this energy can be distinguished by the size of their wavelengths, x-rays have very high-frequency wavelengths. What Are They? X-rays and named x-rays because Wilhelm C. Roentgen called them X-rays because at first, he did not understand what they were. And X is a scientific symbol for the unknown, and they were unknown because he discovered them accidentally while experimenting with vacuum tubes. Why X-Ray's? When In late 1895, a German physicist, W. C. Roentgen was working with a cathode ray tube in his laboratory that is located in Germany. He was working with tubes similar to our fluorescent light bulbs when he discovered x-rays. When Were They Discovered? Where Wilhelm C. Roentgen attended 3 different universities/colleges in Germany, the University of Zurich, the University of Strasbourg, and finally ETH Zurich. But he discovered x-rays while he was a professor at Wuerzburg University in Germany. Where Were They Discovered? How X-rays work by a series of chain reactions. First, an electric current goes through a connection known as a cathode, and then it heats that cathode up. The now heated cathode then releases electrons. A voltage is then spread across the cathode and a connection that is called the anode forces electrons to hit and strike a tungsten target, where these components then produce x-rays. How Are X-Ray's Created? The x-rays then exit the machine through a window and go onto make a physical image of what lies inside of a patient's body. And this happens because the bones absorb more rays than the muscles or internal organs because of the calcium they have i them, so because of this, the bones cast the sharpest white shadow on the plastic or film. Where They Then Go X-rays can be very dangerous and possibly lethal if they are not used by a professional in a controlled environment. They have been known to cause serious conditions such as cancer, skin burns, and anemia. This is why during these scans doctors always make sure to shield the parts of the body that are not being examined so that way less radiation is put into the body overall. How Dangerous Are They? Why Was It Needed? Why + X-rays help in looking at the inside of the body without having to cut open the body or make an incision like in a surgery, because back anytime before the 1800's this is how people were diagnosed. In this way, x-ray helps in diagnosing, monitoring, and treating many medical conditions. Plus X-ray carries very minor risks and the benefits of the x-rays outweigh its risks.

Transcript: X-Rays By: Kate Seater, Zoe Ferrer, Stella Heo, and Zach Golik An Introduction to X-Rays X-Rays are a type of radiation called electromagnetic waves. X-Rays are similar to visible light. Unlike light X-Rays have higher energy and can pass through most objects including the body. X-Rays create pictures of inside your body. The images show the parts of your body in different shades of black and white. Introduction Images X-Rays Frequencies of X-Rays Frequencies of X-rays 2 types of X-rays Soft x-rays and hard X-rays Soft rays have high frequencies (have a low amount of energy) Hard X-rays (high amount of energy) Typically, X-rays have a frequency of 3 x 10 to 3 x 10 Hertz (Hz) 16 19 Wave Lengths of X-Rays Wavelength = .01 to 10 nanometers a nanometer = one billionth of a meter a sheet of paper is 100,000 nanometers thick Wavelength of X-rays Energy of X-rays Because the wavelengths of X-rays are so small, they have high energy. X-rays with higher energy and lower wavelength are called hard X-rays, and soft X-rays have a higher wavelength and less energy. Because X-rays are so strong they can often harm living tissue and cause radiation sickness or cancer. Energy of X-rays Speed of X-Rays Because X-rays are a type of electromagnetic wave, they are a type of light. This means that, inside a vacuum, they travel at the speed of light, which is 670,616,629 miles per hour. Speed of X-rays Speed of X-rays in other Mediums X-rays travel as fast as the speed of light in a vacuum the denser the medium the slower the x-ray or light Same speed as all electromagnetic waves Light travels: 99.8% of the speed of light in air. 75% in water, 67% in glass, and 41% in diamonds Hits medium and scatters Speed of X-rays in other Mediums Some Examples of X-Rays Examples Used in airports as part of security different materials absorb different levels of X-rays allows machine operator to look inside of your bag colors based on how much energy passes through the object objects are sorted into organic, inorganic, and metal X-rays at the Airport Example 1 X-rays at the Airport Visuals X-Rays can be used for medical purposes. The X-Rays allow doctors to see moving images of the internal structures of the patients. X-Rays are still used to identify tumors and help with treat cancer. X-rays can be used to kill cancer cells, but also kill healthy cells. X-rays for Medical Use Example 2 Visuals 2 Visuals Doctor's/Dentists office Bones are denser than skin Denser = more x-rays absorbed Bones absorb enough x-rays to show up on film, skin does not X-Rays at the Doctor's Example 3 Visual 3 Visual 3 Works Cited Works Cited Images Images
