Question

What do electromagnetic waves consist of? (choice)

*frequency
*electric & magnetic fields
*longitude

Answer 1

Electromagnetic waves consist of oscillating electric and magnetic fields, and propagate at the speed of light.

Step-by-step explanation:

Electromagnetic waves consist of oscillating electric and magnetic fields. These waves propagate at the speed of light and can be described as transverse waves. They have different frequencies, wavelengths, and energies, but all travel at the same speed in a vacuum.

Answer 2

Electromagnetic waves consist of both electric and magnetic field waves. The creation of all electromagnetic waves begins with an oscillating charged particle, which creates oscillating electric and magnetic fields.
