Chapter 13, Problem 4RAT

The law of reflection applies to

(a) light.

(b) sound.

(c) both light and sound.

(d) neither light nor sound.

Solution

To determine: The correct option for the statement "The law of reflection applies to".

Answer:

The correct option for the statement "The law of reflection applies to" is option (c).

Explanation:

When a ray is traveling from medium to medium, there is a change that occurs in the direction of light. The phenomenon of change in direction at the interface of two mediums is termed as reflection.

According to the law of reflection, when a ray is reflected from a given surface, then the ray's incidence angle will be equal in magnitude with the reflection angle of that ray.

The reflection phenomenon occurs for both sound and light. So, the law of reflection can be applied for both the light and sound.

Conclusion:

Therefore, the correct option for the statement "The law of reflection applies to" is option (c).
