how many wavelengths are seen in this image of a sound wave?\nthree\nfour\nsix\nten
Answer
Explanation:
Step1: Recall wavelength definition
A wavelength is the distance between two consecutive points in phase (e.g., two compressions or two rarefactions) in a wave.
Step2: Count wavelengths in image
By observing the sound - wave image, we can count the number of complete wave - cycles (from one compression to the next compression). There are four complete wave - cycles visible.
Answer:
four
