CBSE Class 12 Physics – Chapter 10 Wave Optics- Study Materials

Wave optics is one of the most important chapters of CBSE Class 12 Physics. Total weightage of Chapter -9 (Ray Optics and Optical Instruments) and Chapter 10 (Wave Optics) of NCERT textbooks in CBSE Class 12 Physics Board Examination is of 25 Marks.

The chapter Wave Optics is broad and concepts given in this chapter are a little bit complicated. We have divided the notes of this chapter into several parts.  we have provided short and simple notes on the following topics and sub-topics:

•    Huygens Principal

•    Reflection & Refraction of Light Waves using Huygens Principle

•    Coherent & Incoherent Waves

•    Superposition Principal

•    Interference of Light Waves

•    Conditions for Interference

•    Young’s Double Sit Experiment

•    Fringes in Interference Pattern

The short notes given below on the above-mentioned topics and sub-topics are very important for board examination as well as competitive examination.

Introduction

Conditions for Interference

Young’s Double Sit Experiment

Fringes in Interference Pattern

We will study the following topics and subtopics:

o   Diffraction

o    Single Slit Diffraction

o    Diffraction Patterns

o    Effect of Slit Width and Wavelengths on Diffraction Pattern

o    Difference between Interference and Diffraction

o    Resolving Power of Optical Instruments

•    Resolving Power of Telescope

•    Resolving Power of Microscope

 

o    Polarisation

o    Methods of Polarisation

Conceptual questions and numerical based on above-mentioned topics are frequently asked in CBSE board and competitive examination.
