How will you determine refractive index of material of a prism using a spectrometer?

Define refractive index?

The refractive index of diamond is:

How will you determine composition of soil ?

Define absolute refractive index.

Define the term dispersion by a prism and give the reason for its occurrence .Write the formula for refractive index of the material of a prism in terms of the anle ofminimum deviation.

The refracting angle of a prism is 60^@ nd the refractive index of the material of the prism is 1.732.Calculate the angle of minimum deviation.

For which colour,the refractive index of the material of prism is maximum and minimum?

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.

Discuss the phenomenon of refraction through a prism and prove that for a prism: mu=(sin(A + delta_m)//2)/(sin A//2) ,where A is anle of prism, mu s refractive index of the material of prism and delta_m is the ngle of minimum deviation.
