Questions

Can electromagnetic waves exert force over a distance?

Can electromagnetic waves exert force over a distance?

Electromagnetic waves are waves that consist of vibrating electric and magnetic fields. They transfer energy through matter or across space. The fields can exert force over objects at a distance. An electromagnetic wave begins when an electrically charged particle vibrates.

Could gravity be an electromagnetic force?

So the answer to your question is no. Gravity is definitely not part of the electromagnetic spectrum. Properties of the gravitational force are very different to the electromagnetic force, (apart from the 1/r^2 law).

How does an electromagnetic wave begin how does it travel?

Electromagnetic waves are created by the vibration of an electric charge. This vibration creates a wave which has both an electric and a magnetic component. Once the energy of the electromagnetic wave is reemitted by an atom, it travels through a small region of space between atoms.

Are gravity waves electromagnetic waves?

The terms gravitational waves and gravitational radiation are interchangeable in the same way electromagnetic radiation and electromagnetic waves are. To emit gravitational waves an object must be accelerating relative to another source, and if rotating, the mass distribution must change with time.

How do photons exert force?

By transferring their momentum, photons are able to exert a force on an object. Physicists refer to it as an optical force. The higher the frequency of the light, the larger its momentum and, therefore, a stronger force it can exert.

How are gravity and electromagnetic the same?

Gravity is a weak force, but has only one sign of charge. Electromagnetism is much stronger, but comes in two opposing signs of charge. Electromagnetic waves are strongly interacting with normal matter, making them easy to detect; but they are readily absorbed or scattered by intervening matter.

How are gravity and electromagnetic forces similar?

There are many similarities between electromagnetic (EM) radiation and gravitational radiation: both travel at the speed of light; both carry energy away from their sources; both consist of transverse waves with two polarizations.

How are gravity and electromagnetic force different?

Gravity is a weak force, but has only one sign of charge. Electromagnetism is much stronger, but comes in two opposing signs of charge. Electromagnetic fields are generated by slight imbalances caused by small (often microscopic) separations of charge.
