Question

State the formula linking refractive index, angle of incidence and angle of refraction.​

Answer 1

Answer:

If i is the angle of incidence of a ray in vacuum (angle between the incoming ray and the perpendicular to the surface of a medium, called the normal) and r is the angle of refraction (angle between the ray in the medium and the normal), the refractive index n is defined as the ratio of the sine of the angle of ...
