It's used as a Climate classification system.
Answer:
Longitudinal waves are waves that transfer energy parallel to the direction of wave motion.
Transverse waves are waves that transfer energy perpendicular to the direction of wave motion.
Explanation:
First of all, transverse waves are not mechanical waves at all. Longitudinal waves are mechanical waves.
Longitudinal waves are waves that transfer energy parallel to the direction of wave motion. A typical example of longitudinal waves is wave on a spiral spring.
Transverse waves are waves that transfer energy perpendicular to the direction of wave motion. A typical example of a transverse wave is light wave and other electromagnetic waves.
