i. A wave covers a distance equal to the wavelength (λ) during one period (T).
Therefore, the magnitude of the velocity (v) is given by,
Magnitude of velocity = Distance covered/Corresponding time
ii. v = 22/7 i.e., v = λ × (1/T) .....(1)
iii. But reciprocal of the period is equal to the frequency (n) of the waves.
∴ 1/T = n ......(2)
iv. From equations (1) and (2), we get v = nλ
i.e., wave velocity = frequency × wavelength.
