Radio waves, microwaves, infrared, light, ultraviolet, X-rays, and gamma rays are all examples of electromagnetic radiation. All of these waves are a component of the electromagnetic spectrum, which includes radio and television waves. Electromagnetic waves, also known as EM waves, are waves that are produced as a result of vibration of charged particles  between an […]

The wave nature of electrons has been a long-debated topic in the world of physics since it was first deduced by Max Planck in his paper Quantum Theory of Radiation (1901). In this paper, Planck proposed that light energy was emitted from atoms as discrete bundles called quanta, which were the minimum units in light

Electronic waves are representatives of the wave nature of the electron. When an electron beam was passed through a double slit and made to strike a screen that was positioned behind the opening of the slits, an interference pattern was formed. It consisted of light and dark strips. This was done by Thomas Young, and

Electromagnetic radiation (EMR) is a kind of radiation in which electromagnetic (EM) field waves carry radiant energy through space. Electromagnetic radiation includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. The electromagnetic spectrum consists of all these frequencies. Electromagnetic waves are produced when electric particles are accelerated, interacting with and exerting force

Electromagnetic waves are the type of apparent light that empower us to see our general surroundings. There are various types of electromagnetic waves. Some of them are infrared rays, microwaves, gamma rays, ultraviolet rays, etc. Every wave has a distinctive characteristic – frequency and wavelength range. Hence, they are used in different fields.  Maxwell was

The whole distribution of electromagnetic radiation based on frequency or wavelength is referred to as the electromagnetic spectrum. Despite the fact that all electromagnetic waves travel at the speed of light in a vacuum, they do so at a broad range of frequencies, wavelengths, and photon energies. The electromagnetic spectrum includes all electromagnetic radiation and

Microwave is a type of electromagnetic radiation with wavelengths ranging from roughly one metre to one millimetre and frequencies ranging from 300 MHz to 300 GHz. Microwaves are defined differently by different sources; the wide definition above includes both UHF and EHF (millimetre wave) bands. The range between 1 and 100 GHz is a more

Introduction The arrangement of electromagnetic radiations, either in ascending or descending order of the wavelength and frequency, is called the electromagnetic spectrum. The electromagnetic spectrum has various classes of electromagnetic radiation. However, there exists no sharp division between any two radiations, as the classification exists in Ranges. The electromagnetic wave was experimentally discovered by Hertz.

Photoelectric effect: The photoelectric effect is a physical phenomenon that occurs when a metal surface is struck by light of a specific frequency. Heinrich Hertz discovered this phenomenon back in 1887, and later Lenard confirmed it in 1902. Still, there were only a few anomalies since Maxwell’s electromagnetic wave theory of light could not explain
