A microwave oven operates at 2.90 GHz . What is the wavelength of the radiation produced by this appliance?
(Express the wavelength numerically in nanometers.)What is the wavelength of the radiation produced by this appliance?
c = frequency * wavelength
3.00 * 10^8 m/s = (2.90*10^9 Hz) * (wavelength)
wavelength = 0.103 meters
0.103 meters * (1.00*10^9 nanometers / 1 meter) = 1.03*10^8 nanometers is the answer.
