Q
Q: What happens to the light ray when it hits the boundary at the critical angle?
Solution:
At the critical angle, the light ray is refracted at 90°, traveling along the boundary between the two media.
Steps: 5
Show Steps
Step 1: Understand that light travels through different materials, like air and water.
Step 2: Know that when light hits the boundary between two materials, it can either reflect or refract.
Step 3: The critical angle is a special angle where the light ray is at the edge of being refracted or reflected.
Step 4: When the light ray hits the boundary at the critical angle, it is refracted at exactly 90 degrees.
Step 5: This means the light ray travels along the boundary, not going into the second material or reflecting back.
