Question

if sin I/ sin r =constant,what is this constant stands for?​

Answer 1

Answer:

\frac{sin\;i}{sin\;r}=constant=\mu

Where i is the angle of incidence and r is the angle of refraction. This constant value is called the refractive index of the second medium with respect to the first. The following is a diagrammatic representation: Snell's law formula is derived from Fermat's principle
