In layman’s terms electromagnetic radiation is light that travels by oscillating in waves at a constant speed carrying energy. … In layman’s terms, light travels by oscillating in waves at a constant speed carrying energy – interactions with objects vary depending on the energy these waves carry.
What is electromagnetic radiation simple?
(ee-LEK-troh-mag-NEH-tik ray-dee-AY-shun) Radiation that has both electric and magnetic fields and travels in waves. It comes from natural and man-made sources. Electromagnetic radiation can vary in strength from low energy to high energy.
What is called electromagnetic radiation?
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.
What does radiation mean in physics?
Radiation is energy that comes from a source and travels through space at the speed of light. This energy has an electric field and a magnetic field associated with it, and has wave-like properties. You could also call radiation “electromagnetic waves”.
What is electromagnetic radiation Class 11?
Electromagnetic radiation is a flow of energy in which electrical and magnetic fields vary simultaneously. Radio waves, microwaves, infrared light, visible light, ultraviolet light, X-rays and gamma rays are all electromagnetic radiations. … Its wave nature is represented by its velocity, frequency and wavelength.
What is electromagnetic radiation properties?
Properties of Electromagnetic Radiation
Then based on the wavelength of the electromagnetic spectrum, the energy is grouped into different categories. These magnetic and electric waves travel perpendicular to each other and have some characteristics like wavelength, amplitude, and frequency.
What is electromagnetic radiation made of?
Classically, electromagnetic radiation consists of electromagnetic waves, which are synchronized oscillations of electric and magnetic fields. Electromagnetic radiation or electromagnetic waves are created due to periodic change of electric or magnetic field.
What is electromagnetic oscillation?
a coupled oscillation of the electric field E and the magnetic field H that constitute a single electromagnetic field. By nature, an electromagnetic oscillation is an ensemble of photons. … Only when the number of photons is large may such oscillations be considered a continuous process.
What is radiation definition and example?
Radiation is the process of sending off energy in the form of light, heat, x-rays or nuclear particles. An example of radiation are the energy waves off of a nuclear bomb. … The transfer of energy via radiation (as opposed to convection or conduction).
Is all radiation electromagnetic?
Radio waves, gamma-rays, visible light, and all the other parts of the electromagnetic spectrum are electromagnetic radiation.
What is radiation in basic science?
Radiation is energy that comes from a source and travels through space and may be able to penetrate various materials. … The kinds of radiation are electromagnetic (like light) and particulate (i.e., mass given off with the energy of motion). Gamma radiation and x rays are examples of electromagnetic radiation.
What is electromagnetic radiation Class 12?
Electromagnetic radiation is form of energy that is all around us and takes many forms, Such as X rays and gamma rays. Sunlight is also a form of M energy, but visible light is only a small portion of EM spectrum, which contains a broad range of electromagnetic wavelengths.
What is electromagnetic waves in chemistry?
Definition of ‘Electromagnetic Waves’ Definition: Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields.
What is electromagnetic theory in chemistry?
The main points of electromagnetic wave theory were : When an electrically charged particle moves under acceleration, alternating electrical and magnetic fields are produced and transmitted. These fields are transmitted in the form of waves. These waves are called electromagnetic waves or electromagnetic radiations.
