The oscillation of a piston due to air pressure is derived. It is a nonlinear equation... -----Oscillators Playlist ...

Ultimately we need to apply Newton's 2nd law, which applies to point masses. So we consider a small piece (a.k.a. differential ...

The square of the summed fields leads to a cross term, called the "interference term". We begin to simplify it here.

Now we test it. I solve for the initial condition with both an initial displacement and initial velocity. Will it just be the sum of the two ...

Here we see what happens when you put a sinusoid in a

Here we consider the consequences of the new, complex,

Here we see how

Here are some details on how we characterize linear polarizers, plus a bit on what "unpolarized light" means. -----Polarization ...

The

You can see the three optical devices as anisotropy in the refractive index for linear and circular light, but what about circular ...

Here we trace rays through the sphere and find the "magic point" that yields straight rays. -----Geometrical Optics playlist ...

The dirty little secret on how you solve the oscillator's differential equation of motion. We also find what that solution requires: ...
