Question

A wave has a period of 2 seconds and a wavelength of 4 meters. Calculate its frequency and speed.

Note: Recall that the frequency of a wave equals 1/period & the period of a wave equals 1/frequency.

Answer 1

frequency = 0.5 /s

speed = 2m/s

Step-by-step explanation:

frequency = 1/period = 1/2 = 0.5 /s

speed = frequency × wavelength

= 0.5 × 4 = 2m/s
