Statement-I : Coversionof a gamma photon into an electron and a positron is an example of pair production. Statement -II : Pair production refers to the creation of an elementary particle and its antiparticle,usually when a photon interacts with a nucleus.

The positron is a fundamental particle with the same mass as that of the electron and with a charge equal to that of an electron but of opposite sign. When a positron and an electron collide, they may annihilate each other. The energy corresponding to their mass appears in two photons of equal energy. Find the wavelength of the radiation emitted. [Take : mass of electron = (0.5//c^(2))MeV and hc = 1.2 xx 10^(-12) MeV-m , where h is the Planck's constant and c is the velocity of light in air.

Assertion : The energy (E ) and momentum (p) of a photon are related by p = E//c . Reason : The photon behaves like a particle.
