Waves on a Helical Spring

Posted on January 1, 2011 by Arbor Scientific There have been 0 comments

Waves on a Helical Spring Students investigate properties of mechanical waves using a helical spring: wavelength, speed, reflection, standing waves, interference. Neither amplitude nor frequency affects wave speed. As wave frequency goes up, wavelength goes down, and vice versa. Wave pulses can interfere constructively (adding together when on the same side of the spring) or destructively.
