Answer:

v = 0.25m/s

Step-by-step explanation:

Given

$\lambda = 0.02m$ --- Wavelength

T = 8.0 * 10^(-2)s --- Period

Required

Determine the velocity of the wave

This is calculated using:

$v = (\lambda)/(T)$

v = (0.02m)/(8.0*10^(-2)s)

v = (0.02m)/(8.0*0.01s)

v = (0.02m)/(0.08s)

v = 0.25m/s

Hence, the velocity is 0.25m/s
