In a spectrometer experiment, the angle of minimum deviation was found to be `48.6^@`. What is the percentage accuracy in the measurement of refractive index of the prism ? Given least count of spectrometer = `0.2^@` and angle of prism =` 60^@.`

Calculate the refractive index of a prism,if the angle of the prism is 60^@ and the angle of minimum deviation is 30^@ .

A prism is made of glass of unknown refractive index. A parallel beam of light is incident on a face of the prism. The angle of minimum deviation is measured to be 40^@ . What is the refractive index of the material of the prism? The refracting angle of the prism is 60^@ . If the prism is placed in water (refractive index 1.33), predict the new angle of minimum deviation of a parallel beam of light.

How does the angle of minimum deviation of a glass prism of refractive index 1.5 change,if it is immersed in a liquid of refrctive index 1.3?

A thin prism of 2^@ angle gives a deviation of 1^@ . What is the value of refractive index of the material of the prism?

A thin prism of 5^@ angle gives a deviation of 3.2^@ .What is the value of refractive index of teh material of the prism?

A thin prism of 20^@ angle gives a deviation of 1^@ . What is the value of refractive index of the material of the prism?

Angle of minimum deviation for a prism of refractive index 1.5 is equal to the angle of prrism.The angle of prism is

Derive an expression for the anle of deviation of a small prism in terms of the refractive index and the angle of the prism.

What should be the refacting anle of a prism of refractie index 1.5 in order that the ray incident on the face at an angle of 50^@ may suffer inimum deviation.
