In Fraunhofer diffraction from a single slit, wave front incident on the slit is

Diffraction is easily noticeable for sound waves than for light waves because sound waves

Width of slit in a single slit diffraction experiment such that $20$ maxima of double slit interference pattern are obtained within central maxima of the diffraction pattern is (Slit separation for double slit arrangement $=2 \mathrm{mm}$ )

In Fraunhofer diffraction, at the angular position of first diffraction minimum, phase difference (in radian) between wavelets from opposite edges of the slit is

Why a DVD stores almost $30$ times more information than a CD?

Two points separated by $0.05 \mathrm{mm}$ can just be inspected in a microscope when light of wavelength $6000\AA$ is used. If light of wavelength $3000\AA$ is used then the limit of resolution becomes

Unpolarized light of intensity $x$ is incident on a polarising sheet. Intensity of light which does not get transmitted is

Brewster angle for air to water transition is (refractive index of water is $\frac{4}{3}$ )
