A ray of light hits the surface between air and an unknown material at an angle A of 41.1°. It travels through the unknown material at an angle B of 27.7° relative to the vertical. What is the index of refraction of the material?

Refractive index of second material will be 1.41

Explanation:

It is given refractive index of first material, that is air

Angle of incidence = 41.1°

Angle of refraction from second material = 27.7°

We have to find the refractive index of second material.

Now from Snell's law

So refractive index of second material will be equal to 1.4

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
