Question

Does dispersive power of the material of a prism depends upon the shape, size and angle of prism? Explain.

​

Answer 1

We can see that the angular dispersion of a prism is dependent on the angle of the prism but dispersive power does not depend on the geometry of the prism.

Answer 2

The dispersive power of the material of the prism is independent of the shape, angle of prism or size of the prism. It depends only on the refractive index
`{(\mu)}` of the material of the prism.
