Snell's Law
A ray of light is incident on a surface at an angle of 6 0 ∘ , refracts at an angle of 4 5 ∘ . Find it's refractive index.
Round your answer to 3 decimal places.
The answer is 1.225.

Its at the surface ,60 deg, so with the normal 30 degrees answer comes out to be 0.7071
From snell's law we know that: sin r sin i = refractive index = sin 4 5 ∘ sin 6 0 ∘ ≈ 1 . 2 2 5
We wrote the solutions at same time :-P
Refer to Snell's law - n = refractive index.
n = sin60 ÷ sin45
n = (√3/2) ÷ (1/√2)
n = 1.2247... = 1.225 approximately

Mai chala BIO Padhne. BYE.
@Ayon Ghosh ,did you comment on my report, I cannot see, as I hven't yet viewed the solution.
According to Snell's Law ,
Refractive index = sin 4 5 ∘ sin 6 0 ∘ = 2 1 2 3 = 2 3 ∼ 1 . 2 2 5
