'Traveling waves' presentation slideshows

Essential idea: There are many forms of waves available to be studied. A common characteristic of all traveling waves is that they carry energy, but generally the medium through which they travel will not be permanently disturbed.

Java Applet for Plucking strings http://www.falstad.com/loadedstring/ Use log scaling for harmonics, right + left display You can see the missing harmonics when you pluck. You can see the sum of the left-moving and right-moving wave You can see how plucking near the end adds high harmonics

Traveling Waves

Traveling Waves. Wave Equation. For small angles:. Force. mass. accceleration. Wave Equation. Any function y(x,t) will satisfy wave eq as long as x and t appear in the argument in the combination:. tension. velocity. mass/length. Wave Equation.

Vibration and waves

Vibration and waves. A restoring force always pushes or pulls the object toward the equilibrium position Simple harmonic motion -occurs when the net force is proportional to the displacement from the equilibrium point and is always directed toward the equilibrium point.

x = 0

Think of a train carrying sinusoids. Each flatcar carries one sinusoid having length l. If the train is not moving, the phase at any point x is:. If the train is moving:. Phase velocity : the velocity of a point of constant phase on the traveling waveform. -. +. x = 0.
