About the Master Class

This free class will make you tackle any board/jee-main/Neet problem related to the topic of optical Instruments.

It is often seen that students skip the topic of optical Instruments. It's not because it's tough but because it's not been taught well. More often, they remember the formula to solve questions and it works mostly. But whenever the questions becomes tricky and requires basic understanding it becomes hard and students leave the questions. In reality, the topic is easy and beautiful.

I will cover both basic and advanced levels. Student needs to know just basic lens formula and focal length- curvature relationship. 

The discussion will be about :

  1. Eye :.                                                                                                                                                                                              Eye and imgae formation inside our eyes.Power of accomodation and eye sight. Near and far point.
