Given below are two statements:
Statement I: In a Young's double slit experiment, the angular separation of fringes will increase as the screen is moved away from the plane of the slits
Statement II : In a Young's double slit experiment, the angular separation of fringes will inc …

In a Young's double slit experiment set up, the two slits are kept 0.4 mm apart and screen is placed at 1 m from slits. If a thin transparent sheet of thickness $20\mu \mathrm{m}$ is introduced in front of one of the slits then centre bring fringe shifts by 20 mm on the screen …

In two separate Young's double-slit experimental set-ups, two monochromatic light sources of different wavelengths are used to get fringes of equal width. The ratios of the slit separations and that of the wavelengths of light used are $2:1$ and $1:2$ respectively. The correspo …

When an unpolarized light falls at a particular angle on a glass plate (placed in air), it is observed that the reflected beam is linearly polarized. The angle of refracted beam with respect to the normal is $\_\_\_\_$.
(${\tan }^{-1}(1.52)=57.7^{\circ }$, refractive indices of air a …

Given below are two statements:

Statement-I: A plane wave after passing through prism remains as plane wave but passing through small pin hole may become spherical wave.
Statement-II: The curvature of a spherical wave emerging from a slit will increase for increasing slit width. …

In the Young's double slit experiment the intensity produced by each one of the individual slits is $I_0$. The distance between two slits is 2 mm. The distance of screen from slits is 10 m. The wavelength of light is $6000\mathring{A}$. The intensity of light on the screen in front of …
