Question

In a longitudinal wave, amplitude can be measured from the

distance between high pressure areas of the wave called

Answer 1

In a longitudinal wave, the amplitude is measured by the change in pressure between compressions and rarefactions, with the distance between two consecutive compressions or rarefactions defining the wavelength.

Step-by-step explanation:

In a longitudinal wave, the amplitude can be measured from the distance between the high-pressure areas known as compressions and the low-pressure areas known as rarefactions. The amplitude is considered the maximum displacement from the equilibrium position of the medium, indicating the maximum change in pressure from this neutral state. In the context of sound waves, which are a common type of longitudinal wave, this displacement manifests as variations in air pressure. The wavelength in a longitudinal wave is the distance between two consecutive compressions or two consecutive rarefactions.

The relationship between the period (T) and frequency (f) of a wave is directly related to how often the compressions and rarefactions occur over time, with the equation T = 1/f. As the amplitude of a wave increases, so does its energy, which in the case of sound can be interpreted as an increase in volume or intensity.

Answer 2

For longitudinal waves, amplitude is the distance from rest to crest.

Step-by-step explanation:

Longitudinal Waves.

In a longitudinal wave the particle displacement is parallel to the direction of wave propagation.

longitudinal waves properties includes wavelength, amplitude, period, frequency and wave speed. However instead of peaks and troughs, longitudinal waves have compressions and rarefactions.

The amplitude of a wave refers to the maximum amount of displacement of a particle on the medium from its rest position. In a sense, the amplitude is the distance from rest to crest. Similarly, the amplitude can be measured from the rest position to the trough position.

For longitudinal waves, amplitude is the distance from rest to crest.
