Question

If eight water waves pass an ocean buoy each minute, and successive wave crests are 20 m apart, find the wave speed:__________________

Answer 1

The wave speed is calculated below:

Step-by-step explanation:

Given,

number of waves passed per minute = 8

time period = 1 minute = 60 s

distance between successive wave crests = 20 m

waves passing interval per second =
`(8)/(60)`
`s^(-1)`

Now,

wave speed = 20 m ×
`(8)/(60)`
`s^(-1)`

=
`\frac{8}3}` m/s

= 2.67 m/s

Hence the wave speed is 2.67 m/s.
