1. Description
The apparatus for demonstrating waves along a
cord shows how transverse standing waves can be
induced on a cord or string, and can be used to
investigate how their wavelength at a constant
frequency depends on the tension.
The stretched cord is induced to vibrate by a DC
motor driven by a sine-wave generator.
The instrument and accessories can be used to
show that the wavelength
λ of a vibrating cord
under a tension F is halved when the tension is
increased by a factor of four.
