Question

20. Which of the following occurs when light is reflected from a rough or unpolished surface? A. The angle of reflection is less than the angle of incidence. B. The angle of reflection is greater than the angle of incidence. C. The original pattern of the light is distorted. D. The original pattern of the light is preserved.

Answer 1

Answer:C

Step-by-step explanation:

When light strikes a smooth surface it reflects at an equal angle at which it hits the surface but for a rough surface, it reflects in all the directions due to irregularities of surface.

This is the reason why we are not able to see the reflection on the rough surface as the light reflects in random directions. Sometimes it retraces its original path and some it deflects at a higher angle.
