Question

A prism deviates a monochromatic ray of light through an angle δ , where the angle of incidence at

the surface of the prism is i .​

Answer 1

Answer:

Explanation:

In the case of minimum deviation, angle of incidence is equal to angle of emergence. sin = ? A ray EF of monochromatic light is incident on the refracting surface AB of a regular glass prism (refractive index = 1.5) at an angle of incidence of i = 55° (Figure 11).
