White light is used to illuminate the two slits in a Young's double slit experiment. The separation between the slits is b and the screen is at a distance d`(gtb) from the slits. At a point on the screen directly in front of one of the slits, certain wavelength are missing. Some of these missing wavelength are

Options

A. `(b^(2))/(d), (b^(2))/(3d)`
B. `(b^(2))/(d), (b^(2))/(4d)`
C. `(b^(2))/(2d), (b^(2))/(3d)`
D. `(b^(2))/(2d), (b^(2))/(4d)`

Answer

A

Explanation

`x = (2n-1) (lambda D)/(2d)`
