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...
Tuning Fork Interference
Tuning Fork InterferenceTwo waves, when traveling through the same medium, will superimpose upon one another, causing interference. In the case of sound, the two sounds will combine to form a single sound. This lab asks students to combine the sounds...
