counting wavelengths\nhow many complete wavelengths are present in the sound wave shown?\n1\n2\n4\n6
Answer
Explanation:
Step1: Recall wavelength definition
A wavelength is the distance between two consecutive points in phase (e.g., two crests or two troughs).
Step2: Count complete wavelengths
By visually inspecting the sound - wave shown, we can count the number of times the wave pattern repeats itself.
