Lesson: Photon Momentum Physics

Students will be able to

• recognize that photons have momentum, even though they do not have mass,
• recognize that, for one photon, this momentum is very small,
• recognize that the momentum of a photon is inversely proportional to its wavelength,
• recognize that the momentum of a photon is directly proportional to its frequency,
• use the formula ,
• use the formula ,
• find the total momentum of identical photons, given the wavelength or frequency of each photon.
