  • Explain how electromagnetic waves propagate in any medium.

Everything You'll Have Covered

When a charged particle begins to accelerate, what happens to its electrical and magnetic fields?

~ When a charged particle begins to accelerate, its electrical field changes and this creates a changing magnetic field perpendicular to the electric field. This changing magnetic field, in turn, produces a changing electric field, and so on.

What is an electromagnetic wave?

~ An electromagnetic wave is a combination of the perpendicularly propagating electrical and magnetic fields generated as a result of the acceleration of a charged particle.

What are some examples of household appliances that use electromagnetic waves?

~ Some examples of household appliances that use electromagnetic waves include microwave ovens, televisions, and cell phones.
