What Starts an Electromagnetic Wave?
How Are EM Waves Different from Mechanical Waves?
Microwaves have wavelengths between 1 x 10 ⁻³ and 1 x 10 ⁻¹ meters and frequencies between 3 x 10 ⁹ and 3 x 10 ¹¹ Hertz. The energy levels of microwaves are between 2 x 10 ⁻²⁴ and 2 x 10 ⁻²² Joules. Microwaves (the kitchen appliance), astronomers, and satellites all use microwaves when preforming their tasks.
