Question

15. Write the formula of snells law explain the tems?​

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

Explanation:

Snells's law is the formula used to describe the relationship between the angles of incidence and reflection, when referring tu to light or other waves passing through a boundary between two different isotropic media, such as water ,glass,or air .
