Question

A beam of light reflects and refracts at point P ,as shown in the the diagram. Find the angle of refraction at point P. n1 and n2 are refractive indices of the media

Answer 1

Please do mark it as the brainliest if it's correct.

Hope it helps.

Thanks

Answer 2

These type of questions are done generally by Snell’s Law which states that
Sin i / Sin r = n2/n1
Where i = 60
Thus substituting values we get sin r = 0.5 taking sin^-1 we get r = 30
I hope this helps ❤️
