List of top Physics Questions on Wave Optics asked in KEAM

An unpolarized light incident on a plane glass surface gets totally polarized on reflection. If the refractive index of glass is $\tan 57^{\circ}$, then the angle of refraction is:

Pick out the INCORRECT statement from the following:

In Young's double slit experiment, the band width of the fringes observed is \( \beta \), when light of wavelength \( \lambda \) is used. With same experimental set up, to double the band width of the fringes, the wavelength of light required is

An aperture of size \(a\) is illuminated by a parallel beam of light of wavelength \(\lambda\). The distance at which ray optics has a good approximation is

Two plane wavefronts of light, one incident on a thin convex lens and another on the refracting face of a thin prism. After refraction at them, the emerging wavefronts respectively become
