JEE Mains · Physics · STD 12 - 10. Wave optics
The light waves from two coherent sources have same intensity \({I}_{1}={I}_{2}={I}_{0} .\) In interference pattern the intensity of light at minima is zero.What will be the intensity of light at maxima?
- A \({I}_{0}\)
- B \(2 {I}_{0}\)
- C \(5 {I}_{0}\)
- D \(4 {I}_{0}\)
Answer & Solution
Correct Answer
(D) \(4 {I}_{0}\)
Step-by-step Solution
Detailed explanation
\({I}_{\max }=\left(\sqrt{{I}_{1}}+\sqrt{{I}_{2}}\right)^{2}\) \(=4 \,{I}_{0}\)
