The interference pattern is obtained with two coherent light sources of intensity ratio n. In the interference pattern, the ratio $$\frac{I_{max}-I_{min}}{I_{max}+I_{min}}$$ will be

A

$$\frac{2\sqrt{n}}{n+1}$$

B

$$\frac{\sqrt{n}}{(n+1)^2}$$

C

$$\frac{2\sqrt{n}}{(n+1)^2}$$

D

$$\frac{\sqrt{n}}{n+1}$$
