Properties of electromagnetic waves

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

When electromagnetic radiation such as light hits a material like a zinc plate, it leads to the emission of electrons and produces a photoelectric effect. This electromagnetic effect was finally explained by the famous scientist Einstein. However, before him, many other physicists like Heinrich Rudolf Hertz and Lenard observed it and presented it in their

Electromagnetism is a branch of physics that acknowledges electromagnetic force; it is sometimes called a Lorentz force. Electricity, and magnetism are strengths of electromagnetism. Electricity, and magnetism had been lengthy hypotheses to be separate forces. The electric force is the attractive or repulsive force linking two charged particles. Until the nineteenth century, they had been

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

Electromagnetic Waves Electromagnetic waves are the form of visible light that enables us to view the world around us. There are various types of electromagnetic waves out of which you are infrared rays, microwaves, gamma rays, ultraviolet rays, etc. Every wave has a distinctive characteristic, Range of distinctive frequency and wavelength and hence is used

The arrangement of electromagnetic radiations, either in ascending or descending order of the wavelength and frequency, is called the electromagnetic spectrum. Electromagnetic spectrum various classes of electromagnetic radiations are identified, but there exists no sharp, clear-cut division between any two radiations, as the classification exists in ranges. The electromagnetic wave was experimentally discovered by Hertz.
