Prism

Its amazing how physics is a subject which makes you literally run in circles. You think your done with a topic in a particular grade, have written several exams, tests and projects (hopefully passed all of them) , let out a huge sigh of relief , thank god for getting you throught the ride and move on. Wait, but out of nowhere two years later the same topic comes up and says "Hey, You thought your done with me?"

Here I am, Two years later writing about light all over again.

Welcome to the light rollercoaster 2.0 with faster speeds and unnecessarily loopy turns.

And this time we are going to pass light through weird geometrical structures ( cause why not?)

PRISMS

What is a prism?

A prism is a transparent object ( or medium) with two of their surfaces inclined at an angle. This angle is called the 'angle of prism'. < yeah, physicist are not very creative when it comes to naming>

In physics, it isn't necessary for a prism to be 'a prism' (The geometrical one)

But for our purposes, we are going to use the geometrical prism for derivations of all the formulas

( Basically this one 👆)

Displacement method

Now we get into the heads of scientists and figure out how they determine the focal length of convex lens in labs ( cause they aren't ready to empathize with students before making crazy discoveries, we are gonna be the better humans and try to empathize with them instead 🤪)
