Can we create electromagnetic radiation?

No, it is not possible to create magnetic waves without an electric field being present. Electric fields are created by electric charges. For instance, if you statically charged up a balloon by rubbing it on your hair, the balloon creates an electric field.

What causes electromagnetic?

electromagnetic field, a property of space caused by the motion of an electric charge. A stationary charge will produce only an electric field in the surrounding space. If the charge is moving, a magnetic field is also produced. An electric field can be produced also by a changing magnetic field.

How do electromagnetic waves propagate?

The spark current oscillates at a frequency (ν), which is a characteristic of the circuit. The changing magnetic field, in turn, induces an electric field so that a series of electrical and magnetic oscillations combine to produce a formation that propagates as an electromagnetic wave.

What is the electromagnetic field made of?

Electromagnetic fields are made out of photons. The magnitude and direction of the electromagnetic field intensity at any point is directly proportional to the magnitude and direction of the force of the photon at that point.

Which is an electromagnetic radiation?

Electromagnetic radiation is an electric and magnetic disturbance traveling through space at the speed of light (2.998 × 108 m/s). Examples of EM radiation include radio waves and microwaves, as well as infrared, ultraviolet, gamma, and x-rays.

What is electromagnetic radiation in radiography?

Electromagnetic radiation refers to the waves or quanta of the electromagnetic field as they propagate through space. The speed of electromagnetic waves is invariant in a vacuum, being ~3×108 m/s and represented by the symbol, c, otherwise known as the speed of light.

How is a wave propagated and produced?

Waves are generated by wind passing over the surface of the sea. As long as the waves propagate slower than the wind speed just above the waves, there is an energy transfer from the wind to the waves.

Which device produces electromagnetic waves?

Many household appliances produce electromagnetic fields: low consumption light bulbs, television and computer screens, electric radiators and even electric blankets. All of these common objects emit electric or electromagnetic fields and / or function by using them.

What produces electromagnetic radiation?

Electromagnetic radiation is a self-propagating wave of energy that is produced by many contemporary electronic devices. Electromagnetic radiation possesses energy and matter, which is impacted when it encounters another object. This form of energy is thought to possess beneficial, as well as harmful, health effects.

What is electromagnetic radiation has the highest energy?

The highest energy form of electromagnetic waves are gamma (γ) rays and the lowest energy form are radio waves. The figure below shows the electromagnetic spectrum, which is all forms of electromagnetic radiation.

Which electromagnetic radiation has the lowest frequency?

Answer and Explanation: The electromagnetic waves with the lowest frequency are radio waves. The frequency of radio waves ranges from 104 – 109 hertz. With such a low frequency, radio waves also have the longest wavelengths of the electromagnetic spectrum.

What makes electromagnetic radiation?

Electromagnetic radiation is made when an atom absorbs energy. The absorbed energy causes one or more electrons to change their locale within the atom. When the electron returns to its original position, an electromagnetic wave is produced.
