asper made a list of the properties of electromagnetic waves. Identify the mistake in the list.

Question

Electromagnetic Wave Properties
1. Are made up of an electric field and a magnetic field
2. Are longitudinal waves
3. Can travel through space
4. All travel at the same speed in a vacuum

Line 1 has a mistake.

Line 2 has a mistake.

Line 3 has a mistake.

Line 4 has a mistake.

Answer 1

The mistake in the list is in Line 2:

Line 2 has a mistake.

Electromagnetic waves are transverse waves, not longitudinal waves. Longitudinal waves have oscillations that are parallel to the direction of wave propagation (like sound waves), while transverse waves have oscillations that are perpendicular to the direction of wave propagation, which is characteristic of electromagnetic waves.
