Interference of two types
Interference by wave-front and amplitude splitting. Optics Series Lecture, Lecture – XIV, XV, XVI. Topics covered in this lecture A. Color of thin films B. Newton’s rings C. Lloyd’s mirror and D. Phase changes during reflection We have previously discussed what is interference and what are wave-front splitting and amplitude splitting interference. We have also discussed…

Waves
Optics Series Lecture, Lecture – XII and – XIII “Traveling waves, Differential wave equations, Particle and wave velocities.” In one of our earlier optics session lecture I had hinted at having waves defined by their pulse shape called as wave profile — or alternatively wave shape or wave form, and transcribing them into forms that…

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…
