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» 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). |
