# Problem: Microwave ovens emit microwave energy with a wavelength of 12.2 cm. What is the energy of exactly one photon of this microwave radiation?

###### FREE Expert Solution

We have to calculate the energy of one photon in a microwave radiation of wavelength 12.2 cm.

Microwaves are a part of the electromagnetic spectrum.

The relation between the speed, wavelength and frequency of electromagnetic waves is:

We can rearrange this equation to isolate frequency (ν).

The energy of a photon of electromagnetic radiation is given by:

We can replace the frequency (ν) in this equation:

h = Planck’s constant = 6.626x10-34 J·s.

c = speed of light = 3.0x108 m/s
