EM Spectrum

• The electromagnetic spectrum is a range of radiations
• Radio waves have the longest wavelength but the lowest frequency and energy
• Gamma has the highest frequency and energy but the shortest wavelength
• The order of the EM Spectrum from longest to shortest wavelength is: radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, gamma rays
• All parts of the EM Spectrum are transverse waves
• The speed of all EM waves is 3x10^8 m/s
