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(gtgtb)` 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 wavelength are

Options

A. `lambda = (b^(2))/(6d)`
B. `lambda=(2b^(2))/(d)`
C. `lambda = (b^(2))/(3d)`
D. `lambda = (2b^(2))/(3d)`
