In a standard YDSE, distance between slits is d and distance between screen and slit plane is D. The location of 1st maxima for red light is at `y_1` distance from central maxima and for violet is at `y_2` distance from central maxima. Find difference between wavelengths of red and violet lights.

A

`(d(y_1 + y_2))/D`

B

`(d(y_1 - y_2))/2D`

C

`(d(y_1 - y_2))/D`

D
