- Vacuum state
- Empty space
- Magnetic field
- Elastic medium
Show answer and solution
Correct answer: D. Elastic medium
Sound requires an elastic material medium to carry its pressure disturbance.

Worked practice questions
What kind of wave is sound in air?
- Electromagnetic
- Matter-free wave
- Transverse light
- Longitudinal sound
Show answer and solution
Correct answer: D. Longitudinal sound
Sound in air is a mechanical longitudinal wave carried by the fluid.
What vibrates to generate a speaker sound wave?
- Stationary air
- Room wall alone
- Listener eardrum
- Speaker diaphragm
Show answer and solution
Correct answer: D. Speaker diaphragm
A vibrating loudspeaker diaphragm disturbs the surrounding medium.
