Question

Write the formula for the momentum of a photon.

Hint:

The momentum of a photon is inversely proportional to its wavelength.

Answer 1

Step 1: Photon Momentum Formula.
The momentum \( p \) of a photon is related to its energy and wavelength. The formula is: \[ p = \frac{E}{c} = \frac{h}{\lambda} \] where: - \( p \) is the momentum of the photon, - \( E \) is the energy of the photon, - \( c \) is the speed of light, - \( h \) is Planck's constant, - \( \lambda \) is the wavelength of the photon.
