Lesson
Level 3 (with higher mathematics)

## Linearly and Circularly Polarized Electromagnetic Waves

Here you will learn about polarized light, i.e. linearly or circularly polarized electromagnetic waves, and what characterizes them.

Lesson
Level 2 (without higher mathematics)

## Function: the Most Important Concept in Mathematics

What is a function in mathematics? Here the concept of a function is explained but also its types (surjective, injective, bijective).

Lesson
Level 3 (with higher mathematics)

## Drude Model and the Classical Charge Transport in Metals

Drude model establishes the linear relationship between the E-field and the current density, determines the electrical conductivity and mobility.

Lesson
Level 3 (with higher mathematics)

## Lorentz Transformation as Rotation or Lorentz Boost

Here you will learn about the properties of the Lorentz transformation as well as rotations in space and Lorentz boosts.

Lesson
Level 2 (without higher mathematics)

## Uniform Circular Motion and its Important Quantities

Uniform circular motion from physics simply explained - here you will learn about centripetal acceleration and centripetal force and how they arise.

Lesson
Level 2 (without higher mathematics)

## Teltron Tube Experiment and How to Get The Specific Charge of a Particle

Here you will learn how a teltron tube experiment is set up, how it visualizes electron motion, and how you can use it to find out specific charge.

Lesson
Level 3 (with higher mathematics)

## RC Circuit: Charging and Discharging a Capacitor

Here you will learn about the RC circuit. This is a resistor and capacitor connected in series. The capacitor can be charged and discharged via the resistor.

Lesson
Level 2 (without higher mathematics)

## Plate Capacitor: Voltage, Capacitance and Eletric Force

Here the plate capacitor is simply explained. With the help of the capacitor you will learn about the electric voltage, electric field and electric capacitance and how to calculate them for a plate capacitor.
