Michael Fowler UVa A very simple spreadsheet animating the
process. Press and hold the end of thescrollbar. This
spreadsheet plots the motion of a damped oscillator: you can
specify the initial conditions and degree of damping, and find
critical damping. An external driving force is added to the
previous spreadsheet: see how damping and resonance compete.
Find out how the period of a real pendulum varies with the
amplitude. From Vladimir Vasc, in the Kinds of waves in one
dimension: transverse, longitudinal, traveling, standing. How
applying F = ma to a little piece of string leads to an equation
that describes many different waves. What happens to a wave when
it reaches the end of the string? Deriving the Wave Equation for
sound waves in a pipe. Energy density and power in a sound wave
in a pipe. Extending the Wave Equation to higher dimensions.

measurement of the wavelength of light. Finding these forces and
