MHT CET Physics question
Two coherent monochromatic light sources are located at two vertices of an equilateral triangle. If the intensity due to each of the sources independently is at the third vertex, the resultant intensity due to both the sources at that point (i.e. at the third vertex) is (in )
Answer: (D)
Solution
The third vertex is equidistant from both sources, so the path difference is zero and the waves interfere constructively:
