You shine a flashlight on a pond. the light hits the pond at an angle of 70° to the normal of the pond. what is angle between the refracted ray entering the pond and the surface normal of the pond? the index of refraction of water is 4/3 select one of the following: (a) 86.99 (b) 23.4° (c) 35 (d) 44.8 (e) toby

(d)  44.8°

Explanation:

For refraction,  

Using Snell's law as:

Where,  

Θ₁ is the angle of incidence  

Θ₂ is the angle of refraction

n₁ is the refractive index of air which is 1

n₂ is the refractive index of water which is 4/3

Given that angle of incidence = 70°

So,  

Angle of refraction = sin⁻¹ 0.7048 = 44.8°.

i think the answer is a and b
