A ray of light is incident on a prism at an angle of `45^(@)` and passes symmetrically as shown in the figure. Calculate :

the angle of minimum deviation.

A ray is incident on the first prism at an angle of incidence 53^(@) as shown in the figure. The angle between side CA and B'A' for the net deviation by both the prisms to be double of the deviation produced by the first prism, will be:

A ray is incident on the first prism at an angle of incidence of 53^(@) as shown in the figure . The angle between side CA and B'A' for the net deviation by both the prisms to be double of the deviation produced by the first prism , will be

The refracting angle of a prism is 40^(@) . A ray of light is incident at angle 38^(@) and passes in the position of minimum deviation. The angle of minimum deviation is

When light rays are incident on a prism at an angle of 45^(@) , the minimum deviation is obtained. If refractive index of the material of prism is sqrt(2) , then the angle of prism will be

A ray of light is incident on one face of a prism at an angle of 50^(@) with the normal . The ray is deviated by the prism through 42^(@) . What is the angle of the prism , if the angle of emergence is 51^(@) ?
