Electromagnetic Waves

A photon is a type of tiny particle composed of various waves of electromagnetic radiation. Maxwell, in an experiment, found out that photons are simple electric fields that travel through space, have particularly no charge or resting mass and mainly travel at the speed of light. Photons are mainly emitted through charged particle actions, besides […]

Permittivity and permeability are two concepts used in electromagnetic theory. Permittivity is a notion connected to the formation of an electric field, whereas permeability is a concept related to the formation of a magnetic field. Permittivity and permeability are two electromagnetic theory concepts. Permittivity has to do with the formation of an electric field, while

Electromagnetic waves are generally known as light and obey the laws of optics. The physical interaction of electric charges, magnetic moments, and the Electromagnetic field is called geomagnetism. The field can be static or changing. Light is an electromagnetic wave and it obeys the laws of optics. Oersted’s law states that an electric current creates

Electromagnetic waves are radiated by accelerating charged particles. Radio waves have the longest wavelengths among electromagnetic waves. The frequency of radio waves is 300 GHz and less.  Electromagnetic waves were discovered by the Scottish mathematician and physicist James Clerk Maxwell. His mathematical theory, now famously called Maxwell’s equation, predicted the existence of electromagnetic waves by

Modulation Modulation, in PHYSICS, is a method for impressing information (voice, music, picture, or data) on a radio-frequency carrier wave with the aid of using various one or more traits of the wave in accordance with the intelligence signal. There are numerous types of modulation, every type designed to regulate a specific function of the

Depending on the wave prototype of light, physicists assumed that enhancing light amplitude would increase the kinetic energy of discharged photoelectrons while enhancing the frequency would show an increment in the measured current.  On the contrary, experiments stated that enhancing the light frequency and expanding the light frequency causes the increment in the kinetic energy

Maxwell’s equations are one of the most elegant and simple ways to describe the foundations of electricity and magnetism. From them, one can create most of the professional relationships in the field. Because of their concise formulation, they embody a high level of mathematical understanding and are therefore not often introduced in an introductory study

Photons, which are little packets of energy, are produced by light. When the atoms of an object are heated, photons are produced as a byproduct of the heating process. The heat causes the electrons to get excited. This energy is released in the form of a photon, and the number of photons released increases as

Whenever we hear the term microwave, we generally think about the microwave oven in our kitchen. However, the term microwave has a much broader meaning than just being a kitchen appliance.  Microwaves are electromagnetic waves distinguished by a wavelength ranging between 0.04 and 12 inches and a frequency of about 300 GHz. Microwaves are most

Today we are going to discuss the uses of radio waves. To understand the usages of radio waves, we should understand what radio waves are. Radio waves lie in one of the seven regions of the electromagnetic spectrum. Moreover, radio waves have the longest wavelength among the other electromagnetic waves. The wavelength of radio waves
