MHT CET 2022 Physics question
Consider the following statement about interference of light A- When crest of one wave coincides with crest of another wave at a point, this point is a point of destructive interference B- Two coherent sources emit wave of same frequency with constant phase difference Choose the correct option from the following
Answer: (C)
Solution
Statement A is wrong: when a crest meets a crest the displacements add (phase difference , path difference ), producing constructive interference; destructive interference occurs when a crest meets a trough.
