Attenuation in Optical Fiber The major transmission characteristics for an optical fiber: 1. Attenuation 2. Dispersion Attenuation: Signal attenuation (fiber dB loss explained) within the optical fibers, as with metallic conductors,…
How to find LASER (Light Amplification by Stimulated Emission of Radiation) wavelength using a Diffraction Grating in the Lab. For this just take a LASER source, a grating (here grating…
The principle, Construction, and Working The Helium-Neon laser was the first continuous laser. It was invented by Javan, Bennett and Harriot in 1961. The laser has three components Laser medium:…
Carbon dioxide (CO2) gas Laser The carbon dioxide laser (CO2 laser) was one of the earliest gas lasers invented by Kumar Patel of Bell Labs in 1964, is one of…
For the Engineering Physics course, I found this book offers good exposure to optics, electromagnetism, the theory of relativity, nuclear physics, solid-state physics, quantum physics, magnetic properties of solids, superconductivity,…
I start this topic with the concept of absorption and emission first of all where one uses the Atomic Excitation or Electronic Excitation. What do you think when a photon…
Introduction Quincke's Method In this video, I have discussed the calculation of the magnetic susceptibility by using Quincke's experiment. What are the important points for the measurement of the magnetic…
To explain the type of magnetic material and its behavior in the presence of external magnetic field the concept of magnetization play an important role. How the magnetization can be…
An ideal voltage source explanation its equivalence and way to explain in terms of terminal points of view. Its representations and basic form defined.
This problem is related to the particle in a box or in an infinite potential well. Particle representation by a wave function that is mathematical function no physical significance of…
