Q. In Y.D.S.E, when a glass plate $(\mu=1.5)$ of thickness $t$ in introduced in the path of one of the interfering beams (wavelength $\lambda$ ). The intensity at the position where the central maxima occurred previously remains unchanged. The minimum thickness of the glass plate is.

Solution:

Correct answer is (a) $2 \lambda$
