Our Eyes Cannot See Those Kinds Of Energy But There Are Some Cameras That Can See Them The Various Forms Of Light Both Visible And Invisible Are The Electromagnetic Spectrum.
Rainbows Show The Entire Spectrum Of Visible Light The Separate Colors Moving In From The Outer Edges Are Red Orange Yellow Green Blue Indigo And Violet.
Shorter Than Violet Is Called Ultraviolet Light X Rays And Gamma Rays Are Forms Of Light With Even Shorter Wavelengths Than Ultraviolet Light With A Wavelength Longer Than Red.
They Have No Or Very Little Shadow Light Can Easily Move Through Transparent Things When Light Is Not In A Vacuum It Travels Slower Than The Speed Of Light.
The Shorter The Wavelength The More Energy The Light Has The Speed Of Light Does Not Depend On Its Energy Going Through Translucent Objects Can Slow Light Down By A Very Small Amount.
Light And Color Are Forms Of Analog Information However Electronic Cameras And Computer Displays Work With Digital Information Electronic Cameras Or Document Scanners Make A Digital.
Radio Waves Are A Form Of Electromagnetic Radiation With A Wavelength Longer Than Infrared Light The Microwaves That Are Used To Heat Food In A Microwave Oven Are Also A Form Of Electromagnetic Radiation.
Light Makes Up A Part Of Both The Electromagnetic Spectrum And Radiation Given Off By Stars Like The Sun The Light That Comes From The Sun Reaches The Earth And Makes It Bright.
The Spectrum Contains All Of The Wavelengths Of Light That We Can See Red Light Has The Longest Wavelength And Violet Purple Light Has The Shortest Light With A Wavelength.
Whether It Can Be Seen Or Not In A Vacuum The Speed Of Light Is 299 792 458 Meters Per Second Or About 186 282 Miles Per Second This Means It Takes About 7 Minutes For Light To Reach Earth From The Sun.
