Diffraction & I...

Polarised light can be produced by:

The critical angle of a certain medium is \({\sin ^{ - 1}}\left( {\frac{3}{5}} \right)\). The polarizing angle of the medium is

Polaroid glass is used in sun glasses because 

In an experiment of a single slit diffraction, the width of the slit is 1.2 μm and the angular width of central maxima is observed to be equal to π/6. Find the wavelength of light.

Two waves having the intensities in the ratio of 9 : 1 produce interference. The ratio of maximum to the minimum intensity, is equal to

According to Huygens principle of secondary wavelets, each particle at a wave front

In a Young's double slit experiment, waves of wavelength λ, are incident on the two slits in phase. They travel to a point on the screen to produce a second minimum of the interference pattern. The difference in the distance travelled by the waves is: 

Monochromatic light of wavelength 580 nm is incident on a slit of width 0.30 mm. The screen is 2m from the slit. The width of the central maximum is

Young's double slit experiment manifests the

Which nature of light is exposed by its diffraction and interference?
