Question

in Snell's laws sin i / sin r = constant . what is constant​

Answer 1

Explanation:

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. Snell's law formula is derived from Fermat's principle.

Answer 2

Snell's law asserts that n1/n2 = sin α2/sin α1. Because the ratio n1/n2 is a constant for any given wavelength of light, the ratio of the two sines is also a constant for any angle.The constant is a fixed value u will always find by solving sin i/sin r.
