We all are aware of radioactive materials but have you ever wondered what makes them radioactive? A radioactive element is nothing but an unstable atom trying to regain its stability by releasing alpha, beta and gamma rays from the nucleus. Understanding the properties of alpha, beta and gamma rays help us understand a lot about […]

The propagation constant of a light wave can be changed by changing its frequency near the bandgap of a Bragg structure.. A stack of layers with alternate refractive indexes can form a Bragg structure. The propagation constant is the measurement of changes in the amplitude and phase of a sinusoidal electromagnetic wave as it propagates

Polarisation is a phenomenon generated by the wave nature of electromagnetic radiation, according to physics. Sunlight is an example of an electromagnetic wave that travels through the vacuum to reach the Earth. When an electric field interacts with a magnetic field the waves that are produced are known as electromagnetic waves. We will learn about two

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
