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.
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.
