Question

The sound propagates in a gaseous medium as :

• A. transverse waves
• B. longitudinal waves
• C. both (a) and (b)
• D. neither (a) nor (b)

Answer 1

The correct option is B longitudinal waves

Sound is a sequence of waves of pressure which propagates through compressible media such as air or water. Sound propagates as longitudinal waves in gaseous medium. Longitudinal waves are the waves in which the displacement of the medium is in the same direction, or the opposite direction to the direction to the direction of propagation of wave.
