Important Topics and Formulae in Ray Optics and Wave Optics

For all the JEE and other Engineering entrance exam aspirants, Optics continues to be a very important topic. In JEE Physics section, Ray Optics and Wave Optics together carry a weightage of more than 10% of the marks in the JEE past year papers.

So get yourself thorough with the concepts involved and practice numerical problems including the ray diagrams.

Here are the important concepts within the JEE Physics Optics section:

Ray Optics:
Spherical lens numerical, Microscope, Telescope, Ray Diagrams, Snell’s Law, Image Formation by Spherical Mirrors, Reflecting Telescope

Wave Optics:
Diffraction, Huygens Principle, Polarization: Brewster’s Law, Lens Formula, Young’s Double Silt Experiment

Below is a list of the formulae that are involved in various calculations in these two chapters. You can either print and carry these with you for quick reference or save as image on your laptop, smartphone or tablet. These will help you cast a quick but attentive glance to the important topics and formulae from the section ‘Optics’.

1. Spherical Mirror, Snell’s Law and Total Internal Reflection
