Question

# Statement 1:Sound waves cannot propagate through vacuum but light waves can

Statement 2:Sound waves cannot be polarised but light waves can be polarized

- Statement 1 is True, Statement 2 is True; Statement 2 is correct explanation for Statement 1
- Statement 1 is True, Statement 2 is True; Statement 2 is not correct explanation for Statement 1
- Statement 1 is True, Statement 2 is False
- Statement 1 is False, Statement 2 is True

## The correct answer is: Statement 1 is True, Statement 2 is True; Statement 2 is not correct explanation for Statement 1

### Sound waves cannot propagate through vacuum because sound waves are mechanical waves. Light waves can propagate through vacuum because light waves are electromagnetic waves. Since sound waves are longitudinal waves, the particles moves in the direction of propagation, therefore these waves cannot be polarised
