INELASTIC COLLISION:
"The collision in which total momentum is preserved but total K.E of system is not conserved is known as inelastic collision".
It is to be noted that momentum and total Energy are conserved in all types of collision. However K.E is conserved only in elastic collisions.
When an electron makes transition from higher energy level having energy E2(n2) to a lower energy level having energy E1 (n1) then a photon of frequency v is emitted.
