Photon Density In A Light Beam

According to Max Planck energy of photon is

What is a photon? Show that it has zero rest mass or photons can not exist at rest. Explain.

The passage of gamma -rays photons through materials sometimes results in pair production, i.e., the transformation of a gamma -rays photon into a positron and an electron (eachof mass m). What is the maximum wavelength of gamma - ray photons for which pair production is possible? (c = speed of light, h = plank constant)

What is the wavelength of the radiation with photon energy which is the mean value of photon energies of radiations with wavelength lamda_1 = 4000 Å and lamda_2 = 6000 Å ?
