Answer:
30.81°
Explanation:
θ₁ = angle of incidence = 50°
θ₂ = Angle of refraction
n₂ = Refractive index of glass = 1.5
n₁ = Refractive index of air = 1.0003
From Snell's Law
Using Snell's law as:
[tex]n_1\times {sin\theta_1}={n_2}\times{sin\theta_2}[/tex]
[tex]1.0003\times {sin50}={1.50}\times{sin\theta_2}[/tex]
Angle of refraction= sin⁻¹ 0.5122 = 30.81°.
