Question

choose the correct answer
what does the
distance from
\a\ to \b\ in this
longitudinal
wave represent?
frequency
wavelength

Explanation:

In a longitudinal wave, the wavelength is defined as the distance between two consecutive points that are in phase (e.g., two consecutive compressions or two consecutive rarefactions). In the given diagram, the distance from "A" to "B" represents the wavelength. Frequency is the number of waves that pass a given point per unit time and is not represented by a linear distance in the wave diagram.

Answer:

wavelength
