Vedclass · Answer

(D) The fringe width $\beta$ in an interference experiment is given by $\beta = \frac{\lambda D}{d}$,where $\lambda$ is the wavelength of light,$D$ is the distance between the slits and the screen,and $d$ is the distance between the slits.When the chamber is filled with air,the wavelength of light is $\lambda_{air} = \frac{\lambda_0}{\mu_{air}}$,where $\lambda_0$ is the wavelength in vacuum and $\mu_{air} \approx 1.0003$.When the chamber is evacuated,the refractive index becomes $\mu_{vac} = 1$.Since $\mu_{vac}  \lambda_{air})$.As $\beta \propto \lambda$,the fringe width $\beta$ increases when the chamber is evacuated.

Interference was observed in an interference chamber when air was present. Now,the chamber is evacuated and if the same light is used,a careful observer will see:
