A right angled isosceles glass prism is made from glass of refractive index 1.5.Show that a ray of light incident normally on the hypotneuse of this prism is deviated through 180^@ .

The refracting angle of a prism is A and the refractive index of its material is cot A//2 .For a ray of light incident on the prism,find the angle of minimum deviation in terms of A.

The refrating angle of a prism is 40^@ and the refractive index of its material is given by mu=1.25 + b/(delta^2) When a ray of light is incident normally on the face AB of the prism,after refraction through the prism,the ray of light just grazes along the face AC as shown in Fig.3.20. . Find the critical angle for the material of the prism.

The refrating angle of a prism is 40^@ and the refractive index of its material is given by mu=1.25 + b/(delta^2) When a ray of light is incident normally on the face AB of the prism,after refraction through the prism,the ray of light just grazes along the face AC as shown in Fig.3.20. If the wavelength of the incident light is 440 nm,find the value of b.

An equilateral prism of refractive index 1.45 is surrounded by water of refractive index 1.33 .A narrow beam of light is incident normally on one face of the prism.Find the direction of the emergent ray.

A prism is made of glass of unknown refractive index. A parallel beam of light is incident on a face of the prism. The angle of minimum deviation is measured to be 40^@ . What is the refractive index of the material of the prism? The refracting angle of the prism is 60^@ . If the prism is placed in water (refractive index 1.33), predict the new angle of minimum deviation of a parallel beam of light.
