The Brewsters angle $i_b$ for an interface should be:

In a Young' double slit experiment. if there is no initial phase difference between the light from the two slits, a point on the screen corresponding to the fifth minimum has path difference.

Young's double slit experment is first performed in air and then in a medium other than air. It is found that $8th$ bright fringe in the medium lies where $5th$ dark fringe lies in air. The refractive index of the medium is nearly :

In a diffraction pattern due to a single slit of width 'a', the first minimum is observed at an angle $30^{\circ}$ when light of wavelength $5000 \mathring A $ is incident on the slit. The first secondary maximum is observed at an angle of :

A linear aperture whose width is $0.02\, cm$ is placed immediately in front of a lens of focal length $60\, cm$. The aperture is illuminated normally by a parallel beam of wavelength $5 \times 10^{-5} cm$. The distance of the first dark band of the diffraction pattern from the centre of the screen is

At the first minimum adjacent to the central maximum of a single-slit diffraction pattern, the phase difference between the Huygen's wavelet from the edge of the slit and the wavelet from the midpoint of the slit is

In the Young's double slit experiment, the intensity of light at a point on the screen where the path difference $\lambda$ is K,( $\lambda$ being the wavelength of light used). The intensity at a point where the path difference is ${\lambda}/4 $ will be

In Young's double slit experiment, the slits are 2mm apart and are illuminated by photons of two wavelengths $\lambda_1 = 12000 \mathring A $ and $\lambda_2 = 10000 \mathring A.$ At what minimum distance from the common central bright fringe on the screen 2m from the slit will a bright fringe from one interference pattern coincide with a bright fringe from the other ?

A telescope has an objective lens of $10 \,cm$ diameter and is situated at a distance of one kilometre from two objects. The minimum distance between these two objects, which can be resolved by the telescope, when the mean wavelength of light is 5000, $\mathring{A}$ is of the order of

A ray of light travelling in air have wavelength $\lambda$ , frequency n , velocity v and intensity I. If this ray enters into water then these parameters are ${\lambda} $' n ' , v ' and I' respectively. Which relation is correct from following?

Rainbow is formed due to:
