Wave Interference - Short Questions With Answer
Class: 12
1. Can two independent sources of light produce interference?
Ans. Two independent sources cannot be coherent because: Light is emitted by individual atoms and not by the bulk of matter acting as a whole. Even a tiniest source consists of millions of atoms, and emission of light by them takes place independently. Even an atom emits an unbroken wave of above 10-8 second due to its transition from a higher energy state to a lower state.
