1. The problem statement, all variables and given/known data

Standing waves are produced in a string by sources at each end with a frequency of 10.0 Hz. The distance between the third node and the sixth node is 54 cm.

a) What is the wavelength of the interfering waves? b) What is their speed?

2. Relevant equations

I believe I should use: T= 1/f, v=λ/T or v=fλ or v=Δd/Δt

3. The attempt at a solution

Using those equations, write out what each symbol is and what the given value in the question for that is:

Wavelength (λ) = ?
Frequency (f) = 10Hz

It should be more clear then.

Remeaber that the distance between a node and its nearest a connecting node is equal to 1/2λ. Hope this helps :)
