Areas of rarefaction

Answer;

Rarefactions

In a longitudinal wave moving along a spring, what are areas where the coils are farthest apart called Rarefactions.

Explanation;A wave is a transmission of a disturbance from one point to another. It involves the transmission of energy from a source to other points.Waves may classified as longitudinal waves or transverse waves depending on the vibration of particles relative to the wave motion.Longitudinal waves are waves in which the vibration of particles is parallel to the direction of the wave motion, while transverse wave are types of waves in which the vibration of particles is perpendicular to the wave motion.Longitudinal waves creates regions where particles are close together called compressions and regions where particles are farthest apart called rarefactions, while transverse waves creates regions of maximum displacement called crests and troughs.

True, the standard unit for volume is liters which can be represented by either a lower case "l" or a capital "l"
