Q2.Interference effects of light from two sources can be observed if
Answer : Option CExplaination / Solution:
If the two sources are coherent, then the phase difference φ at any point will not change with time and we will have a stable interference pattern; i.e., the positions of maxima and minima will not change with time.
If we have two coherent sources S1andS2 vibrating in phase with same amplitude, then for an arbitrary point P with path difference corresponding to ϕ , the resultant intensity if the intensity due to each is I0 would be
Answer : Option CExplaination / Solution: No Explaination.
