AP Physics 2
13.3 Refraction
BeginnerMCQConceptual23.8k
A horizontal boundary separates a lower region labeled water (n = 1.33) from an upper region labeled air (n = 1.00). A vertical dashed line perpendicular to the horizontal boundary represents the normal line. An incident light ray in the water region travels toward the intersection of the boundary and normal line, forming a 60-degree angle with the normal line. No reflected or refracted rays are shown.
Light ray incident on a water-air interface.
A ray of light traveling in water (\(n_{\text{water}} = 1.33\)) approaches a flat interface with air (\(n_{\text{air}} = 1.00\)) at an angle of incidence of \(60^\circ\) relative to the normal. Given that \(\sin(49^\circ) \approx 0.75\) and \(\sin(60^\circ) \approx 0.87\), does total internal reflection occur, and what is the behavior of the light at the boundary?
