Question

Select One Correct Option from the following: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 ( $\gg$ b) from the slits. At a point on the screen directly in front of one of the slits, certain wavelengths are missing. Some of these missing wavelengths are
(A) $\lambda=\frac{b^{2} }{d}$
(B) $\lambda=\frac{2b^{2} }{d}$
(C) $\lambda=\frac{b^{2} }{3d}$
(D) $\lambda=\frac{2b^{2} }{3d}$.

Answer 1

b option is correct I think.
