Electromagnetic Radiation

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 2.50GHz . What is the wavelength of the radiation produced by this appliance?

  1. (3.00*10^8)/(2.5*10^9) = 1.2*10^-1(10^9/1) = 1.20*10^8nm
