Hertz and Lenard’s Observations

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 […]

Explanation Of Electromagnetic Force

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

Everything You Need to Know About Radio Waves

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 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

Electromagnetic spectrum

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.

Electromagnetic

Electromagnetic (EM) radiation is a form of energy that surrounds us and takes many forms such as radio waves, microwave, X-ray and gamma rays. Sunlight is also a form of EM energy, but visible light is only a small part of the EM spectrum and contains a wide range of electromagnetic wavelengths. Electricity and magnetism

Einsteins Explaination

The photoelectric effect occurs when a material absorbs electromagnetic radiation and emits electrically charged particles from or within it. The phenomena of a substance (metal) emitting electrons when subjected to suitable frequencies of radiation is known as the photoelectric effect, and the produced electrons are known as photoelectrons. Photons A photon, often known as a quantum,

Einstein’s Explanation of Photoelectric Effect

Einstein explained the photoelectric effect using Planck’s formula. According to Planck’s formula, the light was a beam that had several particles. In this article, we will understand how Einstein explained the photoelectric effect and why earlier scientists failed to do this. Why Did Scientists before Einstein Fail to Explain the Photoelectric Effect? This concept came

Compton Effect

The Compton effect describes the increase in wavelength of photons (X-rays or gamma rays) as a result of scattering by a charged particle (usually an electron). The effect has become one of the cornerstones of quantum mechanics, which describes both the wave and particle aspects of radiation. By treating X-rays as discrete heartbeats, or quanta,
