Statement 1: Sound needs a medium for its propagation.
Statement 2: Sound cannot propagate through vacuum as vacuum does not have particles which can vibrate.

• A. Only statement 1 is true
• B. Only statement 2 is true
• C. Both the statements are true
• D. Both the statements are false

Answer 1

The correct option is C

Both the statements are true

Sound is a mechanical wave which requires a medium for its propagation. In vacuum, no particles are present. Hence, sound cannot propagate through vacuum.
