Question

Toppr Admin · Accepted Answer

Sound waves are mechanical waves- Mechanical waves need medium and elasticity to propagate in the medium- Therefore in the vaccum speed of sound waves will be zero-So answer -quot-D-quot- is correct-

The velocity of sound in vacuum is
$330 m s^{- 1}$
Zero
$332 m s^{- 1}$
$228 m s^{- 1}$

Sound waves are mechanical waves. Mechanical waves need medium and elasticity to propagate in the medium. Therefore in the vaccum speed of sound waves will be zero.
So answer "D" is correct.
