A string of guitar 1.3 m long vibrates with 4 nodes 2 of them at the ends. Find the wavelength and speed of the wave in the string if it vibrates at 500 Hz.
Solution
Given data
Number of nodes = 4 and therefore, umber of loops = 3
Length of the string = L = 1.3 m Frequency = f3 = 500 Hz
Required
Wavelength = λ3 =? Speed of the wave = v =?
Formula
To solve the equation for third harmonic,
To find the velocity of the wave, use the second formula
