Quantum Jump - Is this wen an electron jumps to a higher energy level when absorbed energy and when it falls down and energy is den emitted as light. ? Photodisintegration - Light is made up of photons which travel in the form of waves. wen a high energy photon collides with an atomic nucleus, the nucleus disintegrates, in some cases a neutron is knocked out. But a photon has no mass. Does dis happen becos of the energy it carries?
