Standing Waves MS&T Physics 1135, Lab E6

Objectives Observe and characterize standing waves on a string. Note: The mechanical oscillator consists of a speaker that drives a post up and down. There is a lever at the top of the housing that blocks the path of this rod. DO NOT apply a signal to the oscillator with this lever in place; make sure the rod is able to move freely before you turn on the function generator! MS&T Physics 1135, Lab E6: Standing Waves

Apparatus Here, the string is being vibrated at a near-resonant frequency, so there are no stable nodes or antinodes. MS&T Physics 1135, Lab E6: Standing Waves

Standing Wave: Counting Nodes Here are two different standing waves, with nodes indicated by red arrows. As n increases, the frequencies become harder to find. Here, the string is being vibrated at a near-resonant frequency, so there are no stable nodes or antinodes. MS&T Physics 1135, Lab E6: Standing Waves
