1 Light in certain cases may be considered as a stream of particles called photons Each photon has a linear momentum h where h is the Planck s constant and is the wavelength of the light A beam of light of wavelength is incident on a plane mirror at an angle of incidence 0 Calculate the change in the linear momentum of a photon as the beam is reflected by the mirror
