by Snell’s Law:\text{by Snell's Law:}by Snell’s Law:
n1sinθ1=n2sinθ2n_1\sin\theta_1=n_2\sin\theta_2n1sinθ1=n2sinθ2
sinθ2=n1sinθ1n2=1.04sin83°2.1≈0.4915sin\theta_2=\frac{n_1\sin\theta_1}{n_2}=\frac{1.04\sin83\degree}{2.1}\approx0.4915sinθ2=n2n1sinθ1=2.11.04sin83°≈0.4915
θ2=29.44°\theta_2 = 29.44\degreeθ2=29.44°
Answer: θ2=29.44°\text{Answer: }\theta_2 = 29.44\degreeAnswer: θ2=29.44°
