Lesson: Propagating Electric and Magnetic Fields

In this lesson, we will learn how to model electromagnetic waves as propagating electric and magnetic fields.

Worksheet: 7 Questions

Q1:

At what speed do electromagnetic waves propagate in a vacuum? Answer to two significant figures.

Q2:

Which of the following statements about the energy transferred by the electric and magnetic fields that electromagnetic waves are comprised of is correct?

Q3:
