the answer is c because that is the answer im sure and by the way your welcome
Answer: The angle of refraction is 32°
Explanation:
By snell law, we have that:
n₁*sen(θ₁) = n₂*sen(θ₂)
Where n₁ = 1.5
n₂ = 2.0
θ₁ = 45°.
then we want to find the angle of refraction.
1.5*sin(45°) = 2*sin(x)
x = Asin(1.5*sin(45°)/2) = 32°
I am sorry I can only answer 7 for you.
Hope it helps
