Question

Standing Waves:

Calculate the mass density of the following string: m=35.0 g L=75cm Mass per unit length= ?? kg/m

Knowing the velocity of a wave in the string, we can calculate the frequencies and wavelengths of the harmonics in the string using: wavelength_n=2L/n f_n=f_1

f_1=v/2L (n=1,2,3...)

Draw the standing wave and calculate the wavelength and frequency for the following harmonics, assuming a string with a length of 2.0 m.

Harmonic number Wavelength Frequency Draw the standing wave

n=1 Wavelength_1=? f_1=?   ?

n=2 Wavelength_2=? f_2=? ?

n=3 Wavelength_3=? f_3=? ?

n=4 Wavelength_4=? f_4=? ?

n=5 Wavelength_5=? f_5=? ?
