A ray of light is normally incident on one face of an equilateral glass prism. Answer the following : (a) What is the angle of incidence on the first face of the prism? (b) What is the angle of refraction from the first face of the prism ? (c) What will be the angle of incidence at the second face of the prism ? (d) Will the light ray suffer minimum deviation by the prism ?

The refracting angle of a prism is 60^(@) and the refractive index of its material is sqrt((7)/(3)). Find the minimum angle of incidence of a ray of light falling on one refracting face of the prism such that the emerging ray will graze the other refracting face.

In figure, a ray of light PQ is incident normally on the face AB of an equilateral glass prism. Complete the ray diagram showing its emergence into air after passing through the prism. Take critical angle for glass= 42^(@) . (a) Write the angles of incidence at the faces AB and AC of the prism. (b) Name the phenomenon which the ray of light suffers at the face AB, AC and BC of the prism.

A ray PQ incident on face AB of a prism ABC , as shown in Fig., emerges from the face AC such that AQ = AR . Draw the ray diagram showing the pasage of the ray through the prism. If the angle of prism is 60^@ and refractive index of the material of the prism is sqrt(3) , determine the values of angle of incidence and angle of deviation. .

A ray of light enters the face AB of a glass prism of refractive index mu at an angle of incidence i . Find the value of i such that no ray emerges from the face AC of the prism, given angle of prism is A .

A ray of light the face AB of a glass prism of refractive index mu at an angle of incidence i . Find the value of i such that no ray emerges from the face AC of the prism. Given angle of prism is A .

The refractig angle of a prism is A and the refractive index of its material is mu .When a ray of light is incident 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.3.21. Determine the value of the angle of incidence in terms of A and mu .
