How can vibrations produce an electromagnetic wave?

Electromagnetic waves are created by the vibration of an electric charge. … The absorption of energy causes the electrons within the atoms to undergo vibrations. After a short period of vibrational motion, the vibrating electrons create a new electromagnetic wave with the same frequency as the first electromagnetic wave.

How electromagnetic waves can be produced?

Electromagnetic waves are produced whenever electric charges are accelerated. This makes it possible to produce electromagnetic waves by letting an alternating current flow through a wire, an antenna. The frequency of the waves created in this way equals the frequency of the alternating current.

Do vibrating electrons produce electromagnetic waves?

Actually atoms itself doesn’t produce em waves because em waves are produced by vibrating or moving electric charge . So atoms contain electrons so if atoms absorb energy the electrons inside it vibrate and hence they can produce em waves.

Which produces the electric field in an electromagnetic wave?

The electric field is produced by stationary charges, and the magnetic field by moving charges (currents); these two are often described as the sources of the field. The way in which charges and currents interact with the electromagnetic field is described by Maxwell’s equations and the Lorentz force law.

What type of electromagnetic waves is produced when electrons vibrate in an antenna?

1) Electricity flowing into the transmitter antenna makes electrons vibrate up and down it, producing radio waves.

Is electricity caused by vibrations?

Theoretically, all vibration energy can be converted into electrical energy. However, there are certain types of vibrations the are preferred when the intent is to power a sensor or monitoring system. They have the following characteristics: A steady vibration (i.e. not random shocks)

What rays are produced by vibrations in the nucleus of an atom?

In nuclear fission, the unstable nucleus breaks into fragments, which are themselves complex nuclei, along with such particles as neutrons and protons. The resultant stable nuclei or nuclear fragments are usually in a highly excited state and then reach their low-energy ground state by emitting one or more gamma rays.

What is produced when electric and magnetic fields vibrate together?

A vibrating electric field, in turn, creates a vibrating magnetic field. The two types of vibrating fields combine to create an electromagnetic wave.

Which component exists in an electromagnetic wave?

The two components of the electromagnetic wave are the electric field and magnetic field. The electric field is formed due to the flow of voltage and the magnetic field from the flow of current. Electromagnetic waves are transverse in nature. The electric and magnetic field are perpendicular to each other.

What are the basic sources of electromagnetic waves?

Sources of Electromagnetic Radiation

  • solar radiation, in other words natural radiation that originates from the sun.
  • terrestrial radiation, in other words natural radiation emitted by the Earth’s surface.
  • artificial radiation originating from a remote sensing system.

Which of the following forms of electromagnetic waves is used mostly in communication?

While many different types of EMF are used to convey information over distance, the most common are radio waves, also called radiofrequencies.

What electromagnetic wave is sometimes called the invisible heat rays?

He concluded that invisible heat rays reside beyond the red end of the visible spectrum – the infrared. We now know that the visible and infrared radiations are members of a family of radiations called the electromagnetic spectrum.

What type of electromagnetic waves is used in radar?

Radar systems transmit electromagnetic, or radio, waves. Most objects reflect radio waves, which can be detected by the radar system. The frequency of the radio waves used depends on the radar application.
