Theo made a list of the properties of electromagnetic waves. identify the mistake in the list.
electromagnetic wave properties
1. are made up of an electric field and a magnetic field
2. are transverse waves
3. cannot travel through space
4. all travel at the same speed in a vacuum
line 1 has a mistake.

Electromagnetic waves, AKA light, can travel through a vacuum.

The third statement is false.

C . cannot travel through space.

Explanation:

Electromagnetic waves are composed of moving electric and magnetic field at right angle moving in the direction of propagation of wave. These waves have a transverse nature and travel with a constant velocity in vacuum.

Hence of the notes that Theo made in the list, option 3 which says cannot travel through space is incorrect.

Electromagnetic waves do travel in vacuum as they do not need any medium to travel.  They can travel through air, solid materials and through vacuum as well.

yup its correct its: c) b b
