An interference pattern is obtained with two coherent light sources of intensity ratio \(n.\) In the interference pattern, the ratio of their intensities \(\left(\frac{I_{max}-I_{min}}{I_{max}+I_{min}}\right)\) will be:
1.
\(\dfrac{\sqrt{n}}{n+1}\)
2.
\(\dfrac{2\sqrt{n}}{n+1}\)
3.
\(\dfrac{\sqrt{n}}{(n+1)^2}\)
4.
\(\dfrac{2\sqrt{n}}{(n+1)^2}\)
