Question

why does a ray incident on a prism deviate away from its base​

Answer 1

Answer:

hello...

Explanation:

your answer is i a ray incident on a prism devites from its path beacuse of change it medium and with the change in refractive index also changes.

For example-

A light ray from air ( lighter medium with refractive index 1 ) goes to a glass ( denser medium with refractive index 1.6 ) deviates from its path.

ADDITIONAL INFORMATION:

And also in case of a prism a white polychromatic light splits into its constituents of different wavelength.

( A plotychromatic light is a light which is made up of different light rays of different wavelength. )
