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.
