Question

A string (L = 0.76 m) was used to generate standing waves. If the number of antinodes generated in the string was 3, the determine the wavelength.

Answer 1

Answer: 0.506 m

Explanation: To solve this we use the relationship for the harmonic in the string which are given by the following expression:

λ=2*L/3

λ=2*0.76 m/3= 0.506 m
