What is the wavelength of a wave whose speed and period are 72.0 m/s and 5.00 s , respectively ?
uranmaximum [27]

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>
