Question

During electronic transition from
higher to lower orbit
1) Absorption of energy occurs n
integral multiple of a unit
2) Absorption of energy occurs in
a continuous manner
3) Emission of energy occurs in
integral multiple of a unit
4) Emission of energy occurs in
continuous manner,​

Answer 1

Answer:

Emission is when electrons return to energy levels. Absorption is when electrons gain energy and jump to higher energy levels. Absorption and emission of light reveals details about the atomic structure of an atom by telling us the amount of energy levels and the space between the energy levels.If a laser-active atom or ion is in an excited state (quantum-mechanical energy level), it may after some time spontaneously decay into a lower energy level, releasing energy in the form of a photon, emitted in a random spatial direction.
