Question

chapter 15 end of chapter review question 19
1 part | -- of 1 point

height of a wave is called the ______.

○ amplitude
○ wavelength
○ pitch
○ frequency

check answer

Explanation:

To solve this, we recall wave - related definitions:

• Amplitude: It is defined as the maximum displacement of a point on a wave from its rest position, which is essentially the height of the wave.
• Wavelength: It is the distance between two consecutive corresponding points on a wave (like two consecutive crests or troughs), not the height.
• Pitch: It is a perceptual property related to the frequency of a sound wave, not related to the height of a wave.
• Frequency: It is the number of waves that pass a fixed point in a given amount of time, not the height of a wave.

So, the height of a wave is called the amplitude.

Answer:

A. amplitude
