Question

The figure shows a Young's double slit experimental setup. It is observed that when a thin transparent sheet of thickness t and refractive index $μ$ is put in front of one of the slits, the central maximum gets shifted by a distance equal to n fringe width. If the wavelength of light used is $λ$ then $t$ will be:

TestHub · Accepted Answer

Shift in central maxima = D a μ - 1 t Fringe width = D λ a It's given, D a μ - 1 t = n D λ a t = n λ μ - 1
