A green light is incident from the water to the air-water interface at the critical angle (theta). Select the correct statement. |

Answer» The entire spectrum of visible light will come out of the water at an angle of `90^@` to the normal. `sinC=(1)/(mu)` …(1)  For the wave of large wavelength (small frequency), refractive index u is small and from EQUATION (1), if u is small, then critical angle C will be large. Hence if light of smaller frequency is REFLECTED then it will refract at less than `90^@`. |
