Question

I NEED HELP PLEASE THANKS! :)
A lifeguard on a beach observes that waves have a speed of 2.60 m/s and a distance of 2.50 m between wave crests. What is the period of the wave motion? Please show all the work

Answer 1

Answer:

0.962 s

Explanation:

Speed = frequency × wavelength

v = fλ

2.60 m/s = f (2.50 m)

f = 1.04 Hz

Period = 1 / frequency

T = 1/f

T = 1 / (1.04 Hz)

T = 0.962 s
