Solution
The correct option is D
Longitudinal progressive
Correct option is D: Longitudinal progressive
Explanation:
Sound travel in air in the form of longitudinal progressive wave.
Explanation of incorrect option:
Longitudinal stationary: Longitudinal stationary waves form when two identical longitudinal waves travelling in opposite directions superimpose.
Transverse progressive: Transverse progressive waves are waves where the displacement of the particles in the medium is perpendicular to the direction the wave is travelling in.
Transverse stationary: A transverse stationary wave is formed when two identical transverse waves travelling in opposite directions superimpose.
