PHYSICS: CHAPTER 10

Take your pens, take your notes, it’s going to be an easy ride!

Too much?

Wave front and Huygen’s principle

Reflection and refraction of plane wave at a plane surface using wave fronts : Proof of laws of reflection and refraction using Huygen’s principle

Interference

Young’s double slit experiment and expression for fringe width

Coherent sources and sustained interference of light

Diffraction due to a single slit

Width of central maximum

Resolving power of microscope and astronomical telescope

Polarisation

Don’t get too happy. This is not the vibe. We are not on an exploration trip. We are in for a war. That’s the mindset.

Plane polarised light

Brewster’s law

Uses of plane polarised light

Polaroids
