Monochromatic light is incident on a glass prism of angle A. If the refractive index of the material of the prism is , a ray, incident at an angle , on the face AB would get transmitted through the face AC of the prism provided:
A ray is incident at an angle of incidence on one surface of a small angle prism (with angle of prism ) and emerges normally from the opposite surface. If the refractive index of the material of the prism is , then the angle of incidence is nearly equal to:
The angle of incidence for a ray of light at a refracting surface of a prism is . The angle of prism is . If the ray suffers minimum deviation through the prism, the angle of minimum deviation and refractive index of the material of the prism respectively, are:
The angle of a prism is . When light is incident at an angle of on the prism, the angle of emergence is . The angle of incidence for which the light ray will deviate the least is such that
A parallel beam of light is incident from air at an angle on the side PQ of a right angled triangular prism of refractive index . Light undergoes total internal reflection in the prism at the face PR when has a minimum value of The angle of the prism is:
Dispersion without deviation is produced by two thin (small angled) prisms which are combined together. One prism has angle and refractive index If the other prism has refractive index what is its angle?
A ray of light is incident at an angle of on one face of a prism of angle . The emergent ray of light makes an angle of with incident ray. The angle made by the emergent ray with second face of prism will be:
A thin prism with angle and made from glass of refractive index is combined with another thin prism made from glass of refractive index to produce dispersion without deviation. The angle of prism for is
A thin prism having refracting angle is made of glass of refractive index 1.42. This prism is combined with another thin prism made of glass of refractive index 1.7. This combination produces dispersion without deviation. The refracting angle of second prism should be
It was found that the refractive index of material of a certain prism varied as where is the wavelength of light used to measure the refractive index. The same material was then used to construct a thin prism of apex angle . Angles of minimum deviation of the prism were recorded for the sources with wavelengths and respectively. Then
