Electromagnetic Radiation Definition

In general radiation only acts over long distances with the magnetic and electric fields acting over short distances. Electromagnetic radiation is radiant energy that includes radio waves microwaves visible light x-rays and gamma rays which differ in their frequencies and wavelengths.

Electromagnetic radiation is commonly referred to as light EM EMR or electromagnetic waves.

Electromagnetic radiation definition. Definitions of electromagnetic radiation noun radiation consisting of waves of energy associated with electric and magnetic fields resulting from the acceleration of an electric charge. Electromagnetic radiation energy unassociated with matter that is transmitted through space by means of waves electromagnetic waves traveling in all instances at 310 10 cm or 186284 miles per second but ranging in length from 10 11 cm electrical waves to 10 12 cm cosmic rays and including radio waves infrared visible light and ultraviolet x-rays and gamma rays. Electromagnetic radiation is energy emanated radially formed through the combined vibration of electrical and magnetic fields.

The wave phenomenon in electromagnetic radiation is given by a wave in the electric field and in the magnetic field. It is a phenomenon both wave and corpuscular. The waves propagate through a vacuum at the speed of light.

There are a few exceptions. Electromagnetic waves are waves that contain an electric field and a magnetic field and carry energy. NCIs Dictionary of Cancer Terms provides easy-to-understand definitions for words and phrases related to cancer and medicine.

What Is Electromagnetic Radiation. This field includes the study of both visible and invisible light. This type of energy does not require a medium in order to propagate meaning that it can travel in the vacuum of space unlike sound which requires matter such as air in order to propagate.

MeSH Emission or propagation of electromagnetic energy wavesrays or the wavesrays themselves. It contains neither mass nor charge but travels in packets of radiant energy called photons or quanta. Electromagnetic radiation in British English noun radiation consisting of self-sustaining oscillating electric and magnetic fields at right angles to each other and to the direction of propagation.

Quantum mechanics developed from the study of electromagnetic waves. In a typical pulse either the electric or the magnetic form will dominate. They travel at the speed of light.

In physics electromagnetic radiation or gamma γ radiation is the radiation of energy in the electromagnetic field. Electromagnetic radiation is an electric and magnetic disturbance traveling through space at the speed of light 2998 108ms. According to classical physics electromagnetic radiation is energy transmitted at the speed of light through oscillating electric and magnetic fields or electromagnetic waves.

Electromagnetic radiation definition radiation consisting of electromagnetic waves including radio waves infrared visible light ultraviolet x-rays and gamma rays. Radiation Electromagnetic n 1. Electromagnetic radiation in classical physics the flow of energy at the universal speed of light through free space or through a material medium in the form of the electric and magnetic fields that make up electromagnetic waves such as radio waves visible light and gamma rays.

Electromagnetic radiation - radiation consisting of waves of energy associated with electric and magnetic fields resulting from the acceleration of an electric charge electromagnetic wave nonparticulate radiation. According to Maxwells equations a pulse of electric energy will always be accompanied by a pulse of magnetic energy. Also according to quantum physics it is described as the wave or flow of photons of the electromagnetic field that propagate or radiate through space or a physical medium carrying electromagnetic radiant energy.

Electromagnetic radiation is self-sustaining energy with electric and magnetic field components.
