Answer: Wavelength is the length of one complete wave cycle (Option C)
Explanation:
Wavelength is the distance between two consecutive crests or troughs. It can be measured by any two consecutive points in a wave. Wavelength is commonly designated by the sign λ (lambda). Wavelength depends on the medium ( for example air, water or vacuum) that a wave travels through.
According to the following wave equation, it can also be deduced that wavelength is inversely proportional to frequency.
V = f λ
V is the speed
F is the frequency
λ is wavelength
