Refraction Index Calculation

The light beam propagates from the first medium with the refractive index n₁ into the second medium with the refractive index n₂.
The angles of incidence and refraction are θ₁ and θ₂ respectively.

The following data are known:
θ₁ = °.
n₂ =
θ₂ = °.
Find unknown n₁.
Enter your answer using 3 significant figures.

n₁ = ?

n₁ sin θ₁ = n₂ sin θ₂
n₁ = n₂ sin θ₂ / sin θ₁

Refraction Calculation: θ1 = ?

n₁ =
n₂ =
θ₂ = °.
θ₁ = ?°

n₁ sin θ₁ = n₂ sin θ₂
sin θ₁ = n₂/n₁ sin θ₂
θ₁ = arcsin( n₂/n₁ sin θ₂ )

Refraction Calculation: θ2 = ?

n₁ =
n₂ =
θ₁ = °.
θ₂ = ?°

n₁ sin θ₁ = n₂ sin θ₂
sin θ₂ = n₁/n₂ sin θ₁
θ₂ = arcsin( n₁/n₂ sin θ₁ )

At what angle?

 35. A narrow beam of white light enters a prism made of crown glass at a θ º incident angle, as shown in Figure. At what angle, θ_R, do the red (660 nm) components of the light emerge from the prism?
