Question

The constant \[\frac{\sin i}{\sin r}\] for a given pair of media is called the:

Options

• refractive index of the first medium with respect to the second medium

• critical angle of the pair of media

• absolute refractive index of vacuum

• refractive index of the second medium with respect to the first medium

Answer 1

In the second law of refraction, the constant \[\frac{\sin i}{\sin r}\] is called the refractive index of the second medium with respect to the first medium.
