We find the magnification, image location, and find out whether the image is real or virtual.

Description: In this video, I go over the different cases where we can use Ampere's Law to find the magnetic field - in particular, when we have an infinite wire, cylinder, and sheet. I discuss *why* this is, and in general what needs to be true to solve for the magnetic field using Ampere's Law. I also go over cases where we cannot use ampere's law, in addition to how to use superposition to solve more complex problems.

I also briefly discuss when phase shifts happen and the equations that underlie them (the Fresnel Equations).

Description: In this video, I describe what optical path length is, in terms of how far light "thinks" it has traveled. I give an expression for the optical path length in terms of the refractive index, and a more general expression if the refractive index varies over space.

Description: In this video, we explore why, when doing ray tracing, we take rays to pass straight through the center of a lens. We zoom in on what exactly happens inside a lens, and figure out what approximations need to be made, and when they break down.
