Answer 2

Answer:

Explanation:

In geometric optics, the angle of incidence is the angle between a ray incident on a surface and the line perpendicular to the surface at the point of incidence, called the normal. ... In the figure below, the line representing a ray makes an angle θ with the normal (dotted linewhere i= angle of incidence

and r= angle of refraction

for calculating refractive index, we should know i and r....and...

the values of their respective sines

On putting the values in the formula we can easily find the refractive inde
