When sunlight is scattered by atmospheric atoms and molecules the amount of scattering of light of wavelength 440 nm is A. Then, the amount of scattering of light of wavelength 660 nm is approximately the amount of scattering of light of wavelength 660 nm is approximately When sunlight is scattered by atmospheric atoms and molecules [...]

Figure shows a mixture of blue, green and red coloured rays incident normally on a right angled prism. The critical angles of the material of the prism for red, green and blue are 46^o , 44^o and 43^o respectively. The arrangement will separate : 44^o and 43^o respectively. The arrangement will separate : Figure shows [...]

Frequencies of light incident on a system of scattering particles are in the ratio of 1:2. Then, the intensity of scattered light in a particular direction is: Frequencies of light incident on a system of scattering particles are in the ratio of 1:2. Then the intensity of scattered light in a particular direction is: November [...]

A given ray of light suffers minimum deviation in an equilateral prism P. Additional prism Q and R of identical shape and of the same material as P are now added as shown in the figure. The ray will now suffer The refractive through the prisms are as shown. Pick out the WRONG statement from [...]

Two beams of red and violet colours are made to pass separately through a prism (angle of the prism is 60^o ). In the minimum deviation position, the angle of refraction inside the prism will be : the angle of refraction inside the prism will be : Two beams of red and violet colours are [...]

White light is incident on face AB of a glass prism. The path of the green component is shown in the figure. If the green light is just totally internally reflected at face AC as shown, the light emerging from face AC will contain the light emerging from face AC will contain White light is [...]

Two glass prisms P1 and P2 are to be combined together to produce dispersion without deviation. The angles of the prisms P1 and P2 ​are selected as 4^o and 3^o respectively. If the refractive index of prism P1 is 1.54, then that of P2 will be A equiangular glass prism of refractive index 1.6 is [...]
