The angle at which a ray of light be incident on one face of an equilateral prism,so that the emergent ray may graze the second surface of the prism is `pi/x` rad.then find "x" ."`(`mu=2`)]

A ray of light is incident at an angle of 50^(@) on one face of an equilateral prism . What is the angle ,which the emergent ray makes with the second face of the prism , if the deviation produced by the prism is 42^(@) ?

(a) Deduce the expression, by drawing a suitable ray diagram, for the refractive index of a triangular glass prisms in terms of the angle of minimum deviation (D) and the angle of prism (A). Draw a plot showing the variation of the angle of deviation with the angle of incidence. (b) Calculate the value of the angle of incidence when a ray of light incident on one face of an equilateral glass prism produces the emergent ray, which just grazes along the adjacent face. Refractive index of prism is sqrt2

When a ray of light is incident normally on one refracting surface of an equilateral prism (Refractive index of the material of the prism =1.5

A monochromatic ray of light is incident normally on one of the refracting surfaces of a prism . The emergent ray grazes the second refracting surface . What is the angle of the prism if the refractive index of the material of the prism is 1.6 ?

A ray of light is incident at an angle of incidence 45^@ on an equilateral prism and emerge at an angle 45^@ then the refractive index of the medium of the prism is:

A ray of light incident at an angle 90° with the face of an equilateral prism passes symmetrically. Calculate the refractive index of the material of the prism

If a light ray incidents normally on one of the faces of the prism of refractive index 2 and the emergent ray just grazes the second face of the prism, then the angle of deviation is

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

A ray of light is incident at 65^(@) on one face of a prism of angle of 30^(@) and the emergent ray makes 35^(@) with the incident ray. The refractive index of the prism is:
