(i) Two sources must emit light of same wavelength (or frequency). (ii) Originating phase difference between two light sources must be either zero or having a constant value, which should not change with time. Class 12 Physics Chapter 10 Wave ...
Yes, law of conservation of energy is strictly followed in interference phenomenon. Of course there is redistribution of energy but there is no net loss or gain of energy in accordance with the conservation law of energy. Class 12 Physics ...
We know that lightwave emitted from an ordinary light source undergoes abrupt phase changes in time intervals of the order of 10-10 s. Thus, the light waves coming out from two independent light sources will not have any fixed phase ...
Light sources which emit light waves of same wavelength (or frequency) having either zero or a constant originating phase difference are called coherent sources of light. Class 12 Physics Chapter 10 Wave Optics Session 2024-2025.
