Write down the formula you shall be using to find the refractive index of the material of the Prism.

Write down the formula of work and heat.

Light from sodium lamp passes through a 60^@ prism. The angle of minimum deviation is also 60^@ . Find the refractive index of the material of the prism for the yellow light.

Draw and discuss abot the i-D curve for a transparent glass prism. Hence derive the formla for the refractive index of the material of the prism.
