Question

the average wavelenght of a wave in a set of ocean waves is 15m. a wave Crest arrives at the shore on average every 10s, making the frequency 0.10Hz. what is the average speed of the waves​

Answer 1

1.5m/s

Step-by-step explanation:

Given parameters:

Wavelength = 15m

Frequency = 0.1Hz

Unknown:

Average speed of the waves = ?

Solution:

To find the average speed,

Average speed = frequency x wavelength

Average speed = 0.1 x 15 = 1.5m/s
