The wavelength at which a thermal radiator at temperature T radiates electromagnetic waves most intensely is given

Question:

The wavelength at which a thermal radiator at temperature T radiates electromagnetic waves most intensely is given by Wien's law: λ max = (2898 μ m ?? K)/T.

(a) Show that the energy E of a photon corresponding to that wavelength can be computed from E = (4.28 x 10-10 MeV/K) T.

(b) At what minimum temperature can this photon create an electron-positron pair (as discussed in Section 21-6)?
