A ray of light passes through three media with refractive indices n1, n2, and n3. If n1 > n2 > n3, which medium has the smallest angle of refraction?
AMedium 1
BMedium 2
CMedium 3
DCannot be determined
✓ Correct Answer: A — Medium 1
By Snell's Law, n*sin(theta) is constant. Larger refractive index corresponds to a smaller angle with the normal.
