Question

Consider the following statements about sound passing through a gas
(a) the pressure of the gas at a point oscillates in time.
(b) the position of small layer of the gas oscillates in time.

• A. both (a) and (b) are correct
• B. (a) is correct and(b) is wrong
• C. (b) is correct and(a) is wrong
• D. both (a) and (b) are wrong

Answer 1

Answer: (A)

both (a) and (b) are correct

Both the statements are correct.

Sound wave is a longitudinal wave and hence pressure and position both will oscillate with time.
