alleryWhich type of wave can air sustain?
AOnly loosened ones
BOnly longitudinal
COnly longstanding
DOnly lopsided ones
Answer & Solution
Correct answer: B. Only longitudinal
1. A gas cannot resist a shearing stress.
2. So one of the two wave types cannot travel in it.
3. In steel both transverse and longitudinal waves propagate, while air sustains only longitudinal waves.
4. So air carries only longitudinal waves.
