How many times a minute does a boat bob up and down on ocean waves that have a wavelength of 43.0 m and a propagation speed of 5.25 m/s?
λ=v/f
f=v/ λ =5.25/43 =0.122 s⁻¹=7.23 min⁻¹
To find out how many times a boat bobs up and down on ocean waves, you need to determine the frequency of the waves. The frequency can be calculated using the formula:
frequency = propagation speed / wavelength
Given that the propagation speed of the waves is 5.25 m/s and the wavelength is 43.0 m, you can substitute these values into the formula:
frequency = 5.25 m/s / 43.0 m
Calculating this gives you the frequency of the waves.
