What are the three longest wavelengths for standing waves on a 220-cm-long string that is fixed at both ends?

Respuesta :

Since the string is fixed at both ends, the wavelengths for standing waves are multiples of the length of the string. The first longest wavelength is 220 cm. The second longest is 2x220 cm = 440 cm. The third is 3x220 cm = 660 cm.
