    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…

This has been started by Brian Cox so if you win over him you can come with “who started first?”. … An entangled electron or any quantum particle…
