Question
When light passes from a denser material to a less dense material
Correct Answer
Option D is the correct answer.
Detailed Explanation
When light passes from a denser optical medium (higher refractive index) to a less dense optical medium (lower refractive index):1. Speed: The speed of light increases because the refractive index is inversely related to the speed of light in the medium (v = c/n).2. Bending: According to Snell's Law (n1sinθ1 = n2sinθ2), if n1 > n2, then sinθ1 < sinθ2, which implies θ1 < θ2 (for angles less than 90°). This means the angle of refraction (θ2) is greater than the angle of incidence (θ1), causing the light to bend away from the normal.
Hint
Recall the relationship between refractive index and speed of light, and how light bends according to Snell's Law when moving between media of different optical densities.
