Which are properties of an electromagnetic wave? Check all that apply. carries energy only through matter travels at the speed of light made of magnetic fields made of electrical fields radiates from a source

2,3,4,5!

properties of electromagnetic waves are as follows

1. travels at the speed of light

All electromagnetic waves can travel at speed of light through vacuum or air.

2. made of magnetic fields

All electromagnetic waves has magnetic field that oscillates perpendicular to the direction of wave

3. made of electrical fields

All electromagnetic waves has electric field that oscillates perpendicular to the direction of wave

4. radiates from a source

these electromagnetic waves are radiated from source in all directions normally outwards
