In young's double slit experiment performed using a monochromatic light of wavelength $\displaystyle \lambda$, when a glass plate $\displaystyle (\mu=1.5)$ of thickness $\displaystyle x \lambda$ is introduced in the path of the one of the interfering beams, the intensity at the position where the central maximum occurred previously remains unchanged. The value of $\displaystyle x$ will be :
Official answer
(2)
$\displaystyle 2$
