MHT CET Physics question
Consider the following statements about interference of light A (1). The interference fringes are equally bright and equally spaced B (2). At the centre of a bright fringe, the intensity is four times the intensity of the incident wave C (3). For constructive interference of two waves, the crest of one wave coincides with trough of another way [MHT-CET 2020]
Answer: (D)
Solution
In Young's experiment the fringes are equally spaced and equally bright (A is true); at a bright fringe , i.e. four times the intensity of
