Two coherent monochormatic light source are located at two vertices of an equilateral trangle. If the intensity due to each of the source independently is `1Wm^(-2)` at the third vertex. The resultant intensity due to both the sources at that point (i.e at the third vertex) is (in `Wm^(-2)` )A. zeroB. `sqrt(2)`C. 2D. 4 |
Answer» Correct Answer - D at the third vertex path diff = 0, hence intensity is max. |
