Microwave radiation has wavelength on the order of 1.0 cm. Calculate the frequency and the energy of a single photon of this radiation. Calculate the energy of an Avogadro's number of photons of this radiation.

Microwave radiation has wavelength on the order of 1.0 cm. Calculate the frequency and the energy of a single photon of this radiation. Calculate the energy of an Avogadro's number of photons of this radiation.

## frequency = speed of light

frequency = speed of light/wavelength.

Energy of photo = hcf where h=Planck's constant, c= speed of light and f=frequency

Enegy of 1 mole of photons = Lhcf where L=Avogadro constant
