Electromagnetic radiation behaves both as particles (called photons) and as waves. wavelength (λ) and frequency (ν) are related according to the equation c=λ×ν where c is the speed of light (3.00×108 m/s). the energy (e in joules) contained in one quantum of electromagnetic radiation is described by the equation e=h×ν where h is planck's constant (6.626×10−34 j⋅s). note that frequency has units of inverse seconds (s−1), which are more commonly expressed as hertz (hz). a microwave oven operates at 2.20 ghz . what is the wavelength of the radiation produced by this appliance?
