Two coherent light waves, each having amplitude 'a', superpose to produce an interference pattern on a screen. The intensity of light as seen on the screen varies between:
- 0 and \(2 {a}^{2}\)
- 0 and \(4 {a}^{2}\)
- \({a}^{2}\) and \(2 {a}^{2}\)
- \(2 {a}^{2}\) and \(4 {a}^{2}\)
Answer
(B) 0 and 4 a ^ 2
