Question

10. A prism deviates a monochromatic ray of light through
of the prism is i'. (i) Draw a diagram showing the
an angle 'S' when the angle of incidence on the surface
variation of 'S' with i'. On your graph show the angle of
minimum deviation. (ii) What is the relation between
the angle of incidence and the angle of emergence
when the ray suffers minimum deviation

when the ray suffers minimum deviation ?
normally on​

Answer 1

Answer:

The above diagram shows the path of light traced when it passes through a prism such that the angle of deviation of light is minimum.

When a light deviates with a minimum amount, angle of incidence i and the angle of emergence e are equal.

Also, the light inside the prism passes parallel to the base of prism BC.
