Types of Radiation
Visible Light
Infrared Light
Gamma Rays
Radio Waves
The Gamma ray is the most powerful wave in the electromagnetic spectrum.
Infrared light is electromagnetic radiation with longer wavelengths than those of visible light
Radio Waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light.
Like all other electromagnetic waves, they travel at the speed of light.
micro waves are used for communication
Microwaves have wavelengths that can be measured in centimeters! The longer microwaves, those closer to a foot in length, are the waves which heat our food in a microwave oven.
When you hear the word radiation, do you think it's a harmful chemical or you can get cancer from it?
Well there's other purposes for this.
Microwaves are good for transmitting information from one place to another because microwave energy can penetrate haze, light rain and snow, clouds, and smoke.
Naturally occurring radio waves are made by lightning, or by astronomical objects, Artificially generated radio waves are used for fixed and mobile radio communication, broadcasting, radar and other navigation systems, Communications satellite, computer networks and innumerable other applications.

microwaves are used in remote sensing. These microwaves are used for radar like the doppler radar used in weather forecasts. Microwaves, used for radar, are just a few inches long.
Ultra violet light is electromagnetic radiation. Although UV light is invisible to our eyes many people are aware of the effects of UV light on the skin. Which is called sunburn and suntan.
radiation is energetic particle or wave
which can come in different ways like
microwaves or gamma rays they can
be harmful as much a they are helpful.
Hot objects glow brighter in the infrared because they put out more heat and more infrared light. Cold objects put out less heat and less infrared light and appear less bright in the infrared.
without radiation we wouldn't have electricity
At airports they have the metal detectors which uses radiation
Even your microwave uses radiation
Even though they can be good to our "everyday life", they can be very harmful.
if you are exposed to radiation so much, you could get cancer
sometimes, you could get so much radiation that you could die instantly

can fight cancer

Visible light waves are the only electromagnetic waves we can see.

ROY-G-BIV is the acronym that represents all of the colors in the visible spectrum of light. R (red) - O (orange) - Y (yellow) - G (green) - B (blue) - I (indigo) - V (violet)
. Not only are those the colors we can see as humans, but they are also in the right order. Red has the longest wavelength and violet has the shortest. You could also say that red is the least energetic and violet is the most energetic of the visible spectrum.

Ultra violet light
Did you ever wonder why when you leave clothing out in the sun its color fades? That is due to ultraviolet light. The rays break down the chemical bonds in the fabric causing the color to fade!
Gamma rays are ionizing radiation and are biologically hazardous. They are produced by the decay from high energy states of atomic nuclei. Natural sources of gamma rays on Earth include gamma decay from naturally occurring radioisotopes. Gamma rays typically have frequencies above 10 exahertz.
