The spectrum of visible light whose frequency is less than that of green light will come out to the air medium. Explanation: sin i_C = 1/n and n prop 1/lambda For greater wavelength (i.e., lesser frequency) n is less. Hence, iC would be more. Thus, these wavelengths will not suffer internal reflection and come out at angles less than $90^\circ$.
