There are seven types of electromagnetic (EM) waves, which make up the electromagnetic spectrum. Electromagnetic waves are transverse waves, and travel at the speed of light. Different types of ...
Today, I used a pedagogical paradigm that I have invented in order to explain to some college students the relationship between mechanical and electromagnetic oscillations in the voltage analogy. A ...
To identify the different parts of a wave. To be able to understand the different graphs used for waves. A transverse wave is one in which the vibrations of the particles are perpendicular (at right ...
