write the of Snell's formula
Answers
Answer:
In the Figure, n1 and n2 represent the indices of refraction for the two media, and α1 and α2 are the angles of incidence and refraction that the ray R makes with the normal (perpendicular) line NN at the boundary. Snell's law asserts that n1/n2 = sin α2/sin α1. Overview of optics and light refraction.
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.
I hope it will be help you ❤️❤️❤️
