Question

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

Answer 1

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

Answer 2

The wave generated due to electric fields is electromagnetic waves. The properties of electromagnetic waves include - travels at the speed of light and made of magnetic fields.

What is an Electromagnetic Wave?

The vibrations caused due to oscillating electric as well as magnetic fields are known as electromagnetic waves. Electromagnetic waves are also produced by the motion of charged particles.

Following are the properties of electromagnetic waves -

• All electromagnetic waves can travel at the speed of light through a vacuum or air.
• Electromagnetic waves have a magnetic field that oscillates perpendicular to the direction of the wave.
• All electromagnetic waves have an electric field that oscillates perpendicular to the direction of the wave.
• Electromagnetic waves are radiated from the source in all directions normally outwards.

Thus, we can conclude that the properties of electromagnetic waves include - travels at the speed of light and made of magnetic fields.
