Fresnel’s Bi-prism; measurement of wavelength of light
Optics Series Lecture, Lecture – XI “Fresnel’s Bi-prism: measurement of wavelength of light by it.” Today we will discuss another interesting interference set-up, now that we have discussed the Young’s double slit experiment, in lecture – IX. A few words about the general mechanism behind interference. There are two kinds of interference basically that we…

Electromagnetic Nature of Light — A brief history of light.
Let us begin this lecture which has roughly two parts; 1. the history of light and its understanding through the centuries and 2. the electromagnetic nature of light A brief history of light Various optical devices and optical phenomena have been known since close to 4000 years. The optical devices of ancient time includes mirrors, burning…

Spherical harmonic waves
In our lecture — VIII, we worked out the form of plane harmonic traveling waves. Note that soon we will have to a. address the concept of wave profile and b. how to convert a wave profile into its corresponding time-dependent or traveling form. But before we do that here is yet another general form of…

Young’s double slit experiment
Optics Series Lecture, Lecture – IX. “Young’s Double Slit Experiment. Coherent Sources and Conditions of Interference” This lecture was delivered on 14th February in a lecture session of 1 and 1/2 hours. This lecture was delivered to Physics elective students. At a later date this was delivered as a lecture to honors students as well. The…

Harmonic plane waves
Optics Series Lecture, Lecture – VIII. “Harmonic Plane Waves” This lecture ( 1.5 hours ) was delivered on 13th February 2017 to honors students In our last lecture ( lecture — VII ) we began by discussing what are electromagnetic waves. We also discussed in good detail what are harmonic waves. Harmonic waves are those waves…
