All About Wave Optics……..

Dear friends,

With the number of posts in the blog growing, I revisited the posts and decided to classify & club the posts pertaining to a unit in a single post. This will facilitate learning & make it enjoyable.The earlier posts in the series clubbed the information about the unit on Electrostatics & Electromagnetic Waves.

Here is All About Wave Optics for you…..

*The Videos

Wave Optics-1   (Nature of light, Introduction to Wave Optics, Wave front, Huygen’s principle, Construction of secondary wave-front)

Wave Optics-2   (Laws of reflection & Laws of refraction using Huygen’s principle)

Wave Optics-3    (Interference of light, Expression of fringe width)

Wave Optics-4    (Diffraction of light)

Wave Optics-5    (Polarisation of Light)

**The Notes

Wave Optics-I (Huygen theory and the derivation of laws of reflection & refraction)

Wave Optics-II (Interference of light)

Wave Optics-III (Diffraction of light)

Wave Optics-IV    (Polarisation of Light) 

***The Assignment

WAVE OPTICS (Assignment)

Happy Learning!

Videos- Polarisation of Light (Wave Optics-5)

The video titled ‘Wave Optics-5’ (Polarisation of Light) describes how the the phenomenon differentiates between Transverse and Longitudinal waves & establishes that light is Transverse in nature.
The topic is very important for the examination.
The video may be viewed by using the link below:

The video is a part of a series aiming at explanation of Wave Optics for CBSE Class 12 students.
All topics in the syllabus in this sub-unit will be covered in subsequent videos.

Optical Instruments

Some of the important diagrams of optical instruments have been included in this post.

Questions based on Optical instruments are generally asked in CBSE class XII examination.

Neat diagrams showing the direction of light rays should be well practiced.

The diagrams drawn here are the ones which the students generally find difficult to draw.

Wave Optics IV

The unit OPTICS is an important part of class 12 C.B.S.E. Physics syllabus. It carries 14 marks constituting 20% of the theory paper.

The sub-unit wave optics is being posted first in four parts. In part I, we covered Huygen theory and the derivation of laws of reflection & refraction. Part II deals with Interference of light and part III the diffraction.

The present part IV deals ith polarisation of light. The phenomenon is easy to understand. Questions based on this phenomenon in the CBSE examination are generally simple.

A few sample questions have also been included for your benefit.

In order to prepare this unit well, repeated written practice is required. Practice the diagrams as well. A neat  and carefully drawn diagram will help you understand the phenomenon better..
