STATEMENT-1 : Fringe width depends upon refractive index of the medium.
STATEMENT-2 :Refractive index changes optical path of ray of light forming fringe pattern.
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
B. Statement - 1 is True, Statement - 2 is True; Statement - 2 is NOT a correct explanation for Statement - 1.
Step-by-step solution
Wavelength in a medium of refractive index (\mu)
(\lambda^{\prime}=\frac{\lambda}{\mu} \text{ where } \lambda \text{ is wavelength in air. })
Fringe width (\omega=\frac{\lambda \mathrm{D}}{\mathrm{d}}).
