The angle of minimum deviation by prism is (180^(0)-2A) .Its critival angle will be

The critical angle of a prism is 30^(@) . The velocity of light in the medium is

The angle of the prism is A and B if the angle of minimum deviation is (180^(@) - 2A) then the refractive index of the material of the prism is

The angle of the prism is A and B if the angle of minimum deviation is (180^(@) - 2A) then the refractive index of the material of the prism is

Minimum angle of deviation for prism having angle prism 30^@ is 30^@ , so find angle of incident.

If 4cos^(2)x=3 and x is an acute angle, find the value of : cos^(2)x+cot^(2)x

The angle of a glass prism is 4.5^(@) and its refractive index is 1.52. The angle of minimum deviation will be

The refractive angle of a prism is 60^(@) . If the prism is immersed in a liquid then the minimum angle of deviation is 30^(@) . Critical angle of glass with respect to the liquid is
