A ray of light travels from air to water. The refeactive index of water is given by the expression
\(\frac{\text{velocity in water}}{\text{velocity in air}}\)
\(\frac{\text{sine of angle of refraction}}{\text{sine of angle of incidence}}\)
\(\frac{\text{apparent depth}}{\text{real depth }}\)
\(\frac{\text{wavelength in air}}{\text{wavelength in water}}\)
Correct answer is D
