Question

A wave has a wavelength of 0.02m and period of 8.0*10^-2 seconds. calculate it's speed. (showing working)​

Answer 1

Answer:

$v = 0.25m/s$

Explanation:

Given

$\lambda = 0.02m$ --- Wavelength

$T = 8.0 * 10^{-2}s$ --- Period

Required

Determine the velocity of the wave

This is calculated using:

$v = \frac{\lambda}{T}$

$v = \frac{0.02m}{8.0*10^{-2}s}$

$v = \frac{0.02m}{8.0*0.01s}$

$v = \frac{0.02m}{0.08s}$

$v = 0.25m/s$

Hence, the velocity is 0.25m/s
