X-Rays

X-Rays have the second shortest wavelength in the EM Spectrum. These waves are used by scientists to study the sun's corona. The leading medical procedures include x-rays to diagnose the body's bones to make sure you are healthy.

X-Rays

Electromagnetic radiation of high energy and very short wavelength (between ultraviolet light and gamma rays) that is able to pass through many materials opaque to light.

Radio Waves

EM Spectrum Presentation

Radio Waves have the longest wavelength of the EM Spectrum,

but it has the lowest frequency

and also have low energy, so

they can't easily harm humans. These waves are used like sonar to determine shapes, sizes, and distances in space. The long wavelength helps us communicate via sattelite and telecommunication.

Radio Waves

An electromagnetic wave of a frequency between about 104 and 1011 or 1012 Hz, as used for long-distance communication.

Goal

Infrared Waves

Spectrum:

In this presentation you will learn all about the EM Spectrum. These include:

  • Radio
  • Micro
  • Infrared
  • Visible
  • Ultraviolet
  • X-ray
  • Gamma

A band of colors, as seen in a rainbow, produced by separation of the components of light by their different degrees of refraction according to wavelength.

Infrared Waves are the third longest wave and frequency in the EM Spectrum. Infrared energy levels are higher than microwaves and sometimes can even be felt. These waves are used to pass through dust in space and allow scientists to see details about the universe.

Infrared

Having a wavelength just greater than that of the red end of the visible light spectrum but less than that of microwaves. Infrared radiation has a wavelength from about 800 nm to 1 mm, and is emitted particularly by heated objects.

Ultraviolet Waves

UV tanning bed

Ultraviolet rays are very useful; they have short wavelengths, but can give you a nice tan if you stay in the sun long enough. Most UV rays come from the sun but can be recreated to use in tanning salons. Professionals using UV telescopes can easily see young stars and find differences in galaxies.

Ultraviolet Waves

Ultraviolet light is electromagnetic radiation with a wavelength shorter than that of visible light, but longer than X-rays, that is, in the range between 400 nm and 10 nm, corresponding to photon energies from 3 eV to 124 eV. ...

Visible Waves

Microwaves

Microwaves have long wavelengths, and they aren't as long as radio waves, but they have a little more energy and frequency than radio waves. Microwaves are most commonly used to heat food in microwaves and ovens. Microwave radiation is also used to determine the origin of the universe.

Visible waves have a short wavelength, but vary with color. The shortest wavelength humans can see is violet and the longest is red; some animals including bees can see colors even we can't see. Visible waves allow scientists to see the elements found in the layers of stars.

Microwaves

Visible waves

An electromagnetic wave within the range of radio frequencies

An electromagnetic wave with a wavelength in the range 0.001–0.3 m, shorter than that of a normal radio wave but longer than those of infrared radiation. Microwaves are used in radar, in communications, and for heating in microwave ovens and in various industrial processes.

Gamma Rays

Gamma rays have the shortest wavelength of the EM Spectrum. Over exposing yourself to gamma rays can lead to serious medical problems, so don't go and try making yourself the Incredible Hulk, okay? Gamma rays have high frequency and energy levels and they come from nuclear fusion from the sun. Gamma rays can give off nuclear fusion which is converted into energy.

Gamma Rays

Penetrating electromagnetic radiation of shorter wavelength than X-rays.
