12th-jee

The impact of an image on the retina remains for

12th-jee

Ability of the eye to see objects at all distances is called

12th-jee

A ray of light incident at an angle 0 on a refracting face of a prism emerges from the other face normally. If the angle of the prism is 5º and the prism is made of a material of refractive index 1.5, the angle of incidence is

12th-jee

A prism of refractive index n and angle A is placed in the minimum deviation position. If the angle of minimum deviation is A, then the value of A in terms of n is

12th-jee

A ray of light is incident at 60° on one face of a prism of angle 30° and the emergent ray makes 30° with the incident ray. The refractive index of the prism is

12th-jee

A ray incident at 15° on one refracting surface of a prism of angle 60°, suffers a deviation of 55°. What is the angle of emergence

12th-jee

When light of wavelength is incident on an equilateral prism kept in its minimum deviation position, it is found that the angle of deviation equals the angle of the prism itself. The refractive index of the material of the prism for the wavelength A is, then

12th-jee

A ray of light passes through an equilateral glass prism in such a manner that the angle of incidence is equal to the angle of emergence and each of these angles is equal to 3/4 of the angle of the prism. The angle of deviation is

12th-jee

The angle of minimum deviation measured with a prism is 30° and the angle of prism is 60°. The refractive index of prism material is

12th-jee

The angle of minimum deviation for a prism is 40° and the angle of the prism is 60°. The angle of incidence in this position will be
