Name The Factors Affecting The Critical Angle For The Pair Of Media
Name the factors affecting the critical angle for the pair of media.
(i) Effect of colour of light: The critical angle for a pair of media is less for the violet light and more for the red light. Thus critical angle increases with increase in wavelength of light.
(ii) Effect of temperature: The critical angle increases with increase in temperature because on increasing the temperature of medium, its refractive index decreases.
