Question

Which rope would have the longest wavelength-one with a frequency of 2 hz or one with a frequency of 3 hz?

Answer 1

The frequency f is related to the wavelength
`\lambda` by the equation

`\lambda = (v)/(f)`
where v is the speed of the wave in the rope.

We can see from the formula that, if v is kept constant, smaller frequency means larger wavelength. So, the rope with frequency 2 Hz will have the longest wavelength.
