MCQs: ELECTROMAGNETIC WAVES, Now in a new format…..

Useful material for entrance tests.
In continuation with the MCQs posted earlier, another lesson on ELECTROMAGNETIC WAVES is being posted.
The MCQs from the lesson have been carefully written/selected to cover various concepts in the unit.
MCQs from some more units units will be posted in due course.
The questions are in a new ppt format.
I will appreciate, if you let me have you critical opinion about the new format viz a viz the earlier one…

All About ELECTROMAGNETIC WAVES…………

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 first post clubbed the information about the unit on Electrostatics followed by a few other units: Current Electricity; Dual Nature of Matter & Radiation & Wave Optics.

In continuation thereof; here is All About ELECTROMAGNETIC WAVES for you…..

PLEASE FEEL FREE TO PROVIDE ANY USEFUL CRITICAL INPUT ABOUT THE POSTS/BLOG.

All About  ELECTROMAGNETIC WAVES

*Minimum Level of learning in ELECTROMAGNETIC WAVES

As this is a very small & easy to understand unit in CBSE Class XII Physics, it is advisable to prepare it thoroughly. In general the questions asked are also direct.So with a little effort; all the three marks may be up for grab.

*The Videos

ELECTROMAGNETIC WAVES-I   (Introduction of Displacement Current; Equality of Conduction & Displacement Currents).

ELECTROMAGNETIC WAVES-II     (Maxwell’s equations; Prediction of E M Waves; Expressions for wave velocity Representation of EM waves & Transverse character ).

ELECTROMAGNETIC WAVES-III    (Production of E M Waves; The Electromagnetic Wave Spectrum)

*The notes

ELECTROMAGNETIC WAVES   

*The Assignment

ELECTROMAGNETIC WAVES

To be posted shortly

It is advisable to revise the unit by trying to solve Previous year papers.

Happy Learning!

Electromagnetic Waves-III

The present video titled EM Waves-III is in continuation of the series aimed at explaining the production & detection of  E M Waves.

The video also explains the various parts of the spectrum of E M Waves, their source  & applications in daily life.

You may click below to watch the video:

Electromagnetic Waves-III    (Production of E M Waves, Detection of E M Waves, E M Spectrum)

For notes, you may search the blog.

After going through the videos, it is advisable to reinforce learning by practicing problems based on the unit.

Happy Learning!

Videos: EM Waves-II

The present video titled EM Waves-II is in continuation of the series aimed at explaining how Maxwell’s equations led him to  prediction of existence of E M Waves. The expressions for wave velocity further justify the correlation of the waves with electric and magnetic fields. The mathematical representation of the waves & their diagrammatic representation showing Transverse character also forms the part of the video.

The production and detection of the waves will be discussed in the next video…

PS: The production and detection of the waves will be discussed in the next video…EM Waves-III

Vidoes: E M Waves-I

The present video titled EM Waves-I marks the beginning of a series aimed at explaining the anomaly in Ampere’s circuital law; modification of the law by Maxwell; Introduction of Displacement current; its relation with conduction current….,characteristics of the waves, EM waves spectrum & the applications of each part.

In this part I, we will be exploring the Inconsistency in Ampere’s circuital law & explanation thereof.
