Ectromagnetic energy refers to the energy transported by electromagnetic waves.
- The amount of energy carried by an electromagnetic wave is directly proportional to its frequency and inversely proportional to its wavelength.
- Radio waves have the longest wavelength and lowest frequency so carry the least energy among electromagnetic waves, while gamma rays have the shortest wavelength and highest frequency in the electromagnetic spectrum and carry the most energy.
- Electromagnetic waves are composed of oscillating electric and magnetic fields that travel through space at the speed of light.
