What is the index of refraction of a refractive medium if the angle of incidence in air is A degrees and the angle of refraction is B degrees?

The index of refraction ( n ) of a refractive medium can be calculated using Snell's Law, which states that ( n = \frac{\sin(A)}{\sin(B)} ), where ( A ) is the angle of incidence in air and ( B ) is the angle of refraction in the medium. Since the index of refraction of air is approximately 1, this formula directly provides the refractive index of the medium. Simply plug in the values of ( A ) and ( B ) to find the result.
