Question

what are electromagnetic? In three pionts

Answer 1

here's your answer looking for

Electromagnetic rays :-

1). electromagnetic rays never showed deflection in electrical or magnetic field.

2). the electromagnetic rays have high penetrating power.

3). these always travel with the velocity of light.

4). at Quantum level it has no mass means it's a massless.

5). electromagnetic rays transmit energy in Quantum called protons.

these electromagnetic rays are as follows:-

gamma rays
Cosmic rays
X rays

Gamma Rays are electromagnetic rays that never shows deflection in electrical or magnetic field.
these rays have high penetrating power.

this can be easily penetrate through our body.

and X-rays are electromagnetic rays that also didn't show deflection in electrical or magnetic field.

these electromagnetic rays forms when the stream of negatively charged particle that is called as electron get strikes any high atomic number element in cathode ray tube.

hope you are satisfied with my answer

Answer 2

Electromagnetism is a branch of physics which involves the study of the electromagnetic force, a type of physical interaction that occurs between electrically charged particles. The electromagnetic force usually shows electromagnetic fields, such as electric fields, magnetic fields, and light. The electromagnetic force is one of the four fundamental interactions in nature.
