(a) Write the expressions for the energy E and the momentum p of a photon in terms of its frequency f and wavelength λ.
(b) Using these expressions, obtain the relation between the energy and momentum of a photon.
(c) By extending the argument used for photons to material particles, prove that the wavelength associated with a particle of linear momentum p is given by λ=ph.
(d) From the final expression, state any TWO conclusions regarding how the wavelength of a material particle varies with (i) its mass and (ii) its speed.
