Answer:
The distance between the two successive crests of the wave is 360m
Explanation:
Wavelength is defined as the property of wave in which the distance between identical points between two successive waves are calculated
Wavelength is referred to as the <em>distance between two successive crests or troughs</em>
<em>Given that:</em>
speed = 72.0 m/s
time = 5 seconds
Using the formula
C = fλ
Where C = speed, f = freequency and λ = wavelength
F = 1 / time
F = 1/5
F = 0.2Hz
From the fomula C = fλ
make λ the subject of the formula
λ = C / f
λ = 72/0.2
<em>λ = 360m</em>
