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

The angle of incidence for a ray of light at a refracting surface of a prism is 45^(@) . The angle of prism is 60^(@) . If the ray suffers minimum deviation through the prism. The angle of minimum deviation and refractive index of the material of the prism respectively, are

The angle of incidence for a ray of light at a refracting surface of a prism is 45^(@) . The angle of prism is 60^(@) . If the ray suffers minimum deviation through the prism, the angle of minimum deviation and refractive index of the material of the prism respectively, are :

The angel of incidence for a fay of light at a refracting sufrace of a prism is 45^(@). The angle of prism is 60^(@) If the ray suffers minimum deviation through the prism, the angle of minimum deviation and refractive index of the material of the prism repectively, are

The angle of a prism is 60^(@) When light is incident at an angle of 60^(@) on the prism, the angle of emerge is 40^(@) . The angle of incidence i for which the light ray will deviate the least is such that

If the refracting angle of a prism is 60^@ and the minimum deviation is 30^@ , then the angle of incidence is

A beam of monochromatic light is incident at i= 50^(@) on one face of an equilateral prism, the angle of emergence is 40^(@) , then the angle of minimum deviation is :
