Because of effect of colour and effect o temperature, critical angle of a pair of refracting media varies with increase in wavelength of incident light

Critical angle is inversely proportional to refractive index and refractive index is inversely proportional to velocity of light in medium and velocity is directly proportional to wavelength of incident light. So critical angle is directly proportional to wavelength of light.
