The quantum of radiation is called a photon. Its characteristics are: (i) The momentum of a photon is given by p = $\frac { {\rm {h}}} {\lambda }$. (ii) The rest mass of photon is zero. Hence, a photon cannot be at rest. 2. The electrons obtained from the photoelectric effects are called photoelectrons.
