7. (a) Distinguish between longitudinal and transverse waves. Longitudinal waves: These are waves in which the particles of the medium oscillate parallel* to the direction of wave propagation. They consist of compressions (regions of high density and pressure) and rarefactions (regions of low density and pressure). An example is sound waves. Transverse waves: These are waves in which the particles of the medium oscillate perpendicular* to the direction of wave propagation. They consist of crests (points of maximum upward displacement) and troughs (points of maximum downward displacement). An example is light waves or waves on a string. The key distinction is the direction of particle oscillation relative to the direction of wave propagation. In longitudinal waves, they are parallel, while in transverse waves, they are perpendicular.
