If angle of incidence, emergence and deviation are `45^(@)`, `55^(@)` and `40^(@)` then the angle of the prism is

A ray of light passes through an equilateral prism in such a way that the angle of incidence is equal to the angle of emergence and each of these angles is 3//4 th the angle of the prism. Determine the (i) angle of deviation and (ii) the refractive index of the prism.

A rays of light passes through an equilateral prism such that the angle of incidence is equal to the angle of emergence and the later is equal to (3//4)th the angle of prism. The angle of deviation is

A ray of light passes through an equilateral prism such that the angle of incidence is equal to the angle of emergence and latter is equal to (3//4)^(th) the angle of prism. The angle of deviation is

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) If the refracting angle of a prism is 60^@ and the minimum deviation is 30^@ , then find the angle of incidence. (b) A ray of light passes through an equilateral prism such that the angle of emergence is equal to the angle of incidence and each is equal to 3//4^(th) of the angle of prism. Find the angle of deviation. (c) The refracting of a prism is A and the refractive index of the material of the prism is cotA//2 . Find the angle of deviation. (d) The angle of a prism is 60^@ . What is the angle of incidence for minimum deviation? The refractive index of the material of the prism is sqrt2 .

A ray of light passes through an equilateral prism such that the angle of incidence is equal of emergence and later is equal to 3/4th the angle of prism. The angle of deviation is
