Light as Waves and Particles - Reflection, Refraction,
Dispersion
Introduction to the Dual Nature of Light
During the 19th and 20th centuries there was a lot of debate about the true nature of light.

Ampere's and Biot-Savart Law
The Biot-Savart Law and Ampere's Law and related in their common function. Both laws can be used to
derive the magnetic field for various arrangements of current-carrying

Introducing Faraday's Law
Introducing Magnetic Induction and Electromotive Force
It is given that a moving charge or current induces a magnetic field, however M
Energy Density
Energy density (u) is the energy per unit volume.
Previously in the course we learned that for electric and magnetic fields, u E = oE2/2 and
uB = B2/2o
For EM waves however the electric
Lenz's Law
Lenz's law describes the direction of the current induced by Faraday's Law. It states that the induced
current in a loop is in the direction such that the resultant magnetic field opposes t
Huygen's Principle
Huygen's principle is a geometric tool which allows us to determine the position of
the wavefront at a point in time based on previous knowledge of the wavefront

Introducing Solenoids
A solenoid is a wire wound in a helix shape, similar to the shape of a slinky, such that

The Magnetic Force Between Parralel Conductors
Consider the following setup:
The force F1 of wire 2 on wire 1 is given by:
Which in this case equates to:

Reflection and Transmission
When a wave strikes a boundary between two media, part of the wave is reflected and part of it
is transmitted. Conservation of energy means that the sum of reflected and tr

Introduction
In 1865, James Clark Maxwell provided a theory which showed the relationship between electric and
magnetic phenomena, from which he derived the idea that li
