occur when waves of slightly different frequencies interfere.
waves are formed when two waves having the same frequency, amplitude,
and wavelength travel in opposite directions through a medium.
waves in a string:
of the harmonics on a string 1.30 m long has a frequency of 15.60
Hz. The next higher harmonic has a frequency of 23.40 Hz. Find
(a) the fundamental frequency, and (b) the speed of waves on this
fundamental frequency is the difference between the given frequencies:
