In this lesson, we will learn how to relate the energy and momentum of photons to the wavelength of electromagnetic waves consisting of such photons.
Sample Question Videos
A photon has an energy of 20.0 keV.
What is this photon’s frequency?
What is this photon’s wavelength?
An AM radio transmitter radiates W of electromagnetic radiation at a frequency of Hz. How many photons per second does the transmitter emit?
In the 1980s, the term picowave was used to describe food irradiation in order to overcome public resistance by playing on the well-known safety of microwave radiation. Find the energy in mega-electron volts of a photon having a wavelength of 1.00 picometer.
