Question
Necessary condition for sustained interference write down.
✓

Answer

(i) Both wave have same frequencies.
(ii) Phase difference doesn't depend on time means it will co-hearent.
(iii) Both wave propagate in same direction in straitght line.
(iv) For rectify interference both wave should have same amplitude but this is not compulsory.
