STATEMENT - 1 : In Young's double slit experiment if whole set up is immersed in a liquid then fringe width is decreased. STATEMENT-2: Wavelength of light entering in a liquid increases.

Options

AStatement -1 is True, Statement -2 is True; Statement -2 is a correct explanation for Statement -1.
BStatement -1 is True, Statement -2 is True; Statement -2 is NOT a correct explanation for Statement -1.
CStatement -1 is True, Statement -2 is False.
DStatement -1 is False, Statement - 2 is True.

Correct answer

C. Statement -1 is True, Statement -2 is False.

Step-by-step solution

\begin{aligned} & \beta^{\prime}=\frac{\lambda_{\mathrm{n}} \mathrm{D}}{\mathrm{~d}} \\ & \lambda_{\mathrm{m}}=\frac{\lambda_{\mathrm{air}}}{\mu} \Rightarrow \beta^{\prime}=\frac{\lambda_{\mathrm{air}} \mathrm{D}}{\mathrm{~d} \mu} ; \beta^{\prime}=\frac{\beta}{\mu} . \end{aligned}
