how many complete wavelengths are present in the sound wave shown?\no 1\no 2\no 4\no 6
Answer
Explanation:
Step1: Identify a wavelength
A wavelength is the distance between two consecutive points in phase (e.g., two crests or two troughs).
Step2: Count wavelengths
By visually inspecting the sound - wave graph, we can count the number of complete up - and - down cycles. There are 6 complete wavelengths.
Answer:
6
