What is the angle of refraction when a ray of light passes from air into diamond at angle i of:
a. 30 degrees
b. 40 degrees
c. 50 degrees

Please include the solution :D :D

Sagot :

a. θ₂=11.9°
b. θ₂=14.4°
c. θ₂=19.3°

n₁(air)=1.0003
n₂(diamond)=2.42
* Sinθ₂=n₁Sinθ₁/n₂
a. Sinθ₂=1.0003 (Sin 30°)/2.42
            =0.50015/2.42
            =0.206673553 or 0.207
         θ₂= Sin⁻¹0.207
         θ₂=11.94° or 11.9°

Just substitute 40° and 50° to get the answer for b and c :)
