3. Superposition and Interference explained

Looks at what superposition is and how it relates to interference from a 1D perspective 

Superposition , or the adding of waves, can be demonstrated and explained by using Desmos a powerful online graphing calculator. This video explains the principles on how to use Desmos as well as the basics of understanding the wave equation. Using Desmos you can show superposition in real time, ie as a function of time (See the DESMOS tab to play with it yourself)

How is information transmitted via an electromagnetic wave. The process is called modulation and in this video I demonstrate two familiar types  amplitude modulation (AM) and frequency modulation (FM)
