Question

In the following questions, a statement of assertion followed by the reason is given. Choose the correct answers out of the following choices:

Assertion: Sound bounces off a solid or a liquid like a rubber ball bounces off a wall.

Reason: Like light, sound gets reflected at the surface of a solid or liquid and follows the same laws of reflection.

• A. Both the Assertion and the Reason are correct and the Reason is the correct explanation of the Assertion.
• B. The Assertion and the Reason are correct but the Reason is not the correct explanation of the Assertion.
• C. Assertion is true but the Reason is false.
• D. The statement of the Assertion is false but the Reason is true.
• E. Both the statements are false.

Answer 1

The correct option is A

Both the Assertion and the Reason are correct and the Reason is the correct explanation of the Assertion.

1. Sound is also a wave just like light.
2. The only difference is, that the sound is a mechanical as well as longitudinal wave, but the light is a non-mechanical as well as a transverse wave.
3. Sound wave bounces off a solid or a liquid like a rubber ball bounces off a wall.
4. This phenomenon is called a reflection of sound waves.
5. Like light, the sound gets reflected at the surface of a solid or liquid and follows the same laws of reflection.
6. Hence, both the statement are true and the Reason is the correct explanation of the Assertion.
7. Thus, the correct option is A.
