II.) Electromagnetic Spectrum A) The Waves of the Spectrum 1) EM spectrum: all of the frequencies or wavelengths of electromagnetic radiation 2) The EM spectrum includes radio waves, microwaves infrared rays, visible light, UV rays, X-rays, and gamma rays. B) Radio Waves -Longest wavelength ...
the electromagnetic spectrum consists of light waves of different frequencies, ex. high-energy high-frequence X-rays (dangerous!) and low-energy low-frequency radio waves (harmless) this includes a narrow strip of the visible spectrum: 700 nm ROYGBIV 400 nm, which we see as a rainbow N.B. ...
