What is Polarisation? Polarisation is a phenomenon that occurs by the electromagnetic wave nature radiation. The sun’s light moves through the vacuum until it reaches the Earth. This could be an instance of an electromagnetic wave.  They are known as electromagnetic waves due to the fact that they arise when an electric field interacts with […]

According to Albert Einstein, electromagnetic energy is contained in quanta or packets, often referred to as photons. In accordance with the earlier observations, the wavelength of light had a huge impact on the electrons that were ejected. Additionally, the intensity of light directly affects the electrons that are released. This is a sign of its

General Modulation is the process of converting data into radio waves by adding information to an electronic or optical carrier signal. A Carrier signal is one that has a constant waveform- constant height, or amplitude, and frequency. Working of Modulation Modulations are often applied to the electromagnetic signals: radio waves, laser / optics and computer

Electromagnetic waves are the form of visible light that enables us to view the world around us. There are various electromagnetic waves such as infrared rays, microwaves, gamma rays, ultraviolet rays, etc. Every wave has a distinctive characteristic, a range of specific frequency and wavelength; hence, it is used in different realms.  Maxwell was the

Introduction  Infrared waves are commonly referred to as thermal or heat waves. These waves consist of heat-inducing properties with the wavelength of infrared waves ranging from 710 mm to 1mm. At times, these waves are categorised into far-infrared or near-infrared rays. Mostly, these waves are used in applications for producing large amounts of heat, such

Infrared light, commonly referred as infrared radiation, is a type of electromagnetic radiation with a wavelength of up to 1050 nm. Since it is much higher than visible light, it can only be recognized by the human eye under certain circumstances. Electromagnetic Waves Everything in our environment, including the sun, the earth, and other bodies, emits

Light is electromagnetic radiation that the human eye can detect. In the 1870s, Maxwell explained that electric fields coupled with magnetic fields produce electromagnetic waves. These waves didn’t require any medium for propagation. Light exhibits both particle and wave behavior. Light exhibits a photoelectric effect as proof of its particle nature. Light as a wave

In Physics, transmission is the method of propagating an analogue or digital signal employing a wired, optical, or wireless magnetic attraction transmission medium. Transmission technologies usually ask physical layer protocol duties like modulation, reception, line committal to writing, feat, error management, bit synchronisation, and multiplexing; however, it’s going to additionally involve higher-layer protocol duties as

A Helmholtz equation is a linear partial differential equation named after Hermann von Helmholtz. Where is the wave number, is the amplitude, and is the laplacian. Eigenvalue equations also include the Helmholtz equation. Helmholtz equation The Helmholtz equation, which is utilised in mathematics and physics, is named after Hermann von Helmholtz. The linear partial differential

Gamma rays are electromagnetic waves with the smallest wavelength (highest energy). The origin of this ray occurs from the smallest atom to the giant celestial body. In the radioactivity chapter, we have learned that it emits gamma rays when an atom shows radioactivity. Besides radioactive decay, it also originated from very hot stars, black holes
