XII-8-2 Electromagnetic waves part -2 (2015) Pradeep Kshetrapal Physics

[@UrvashiVaijwade]

The principle behind how time machine would work was amusing ☺

[@bhavya5508]

this is best lecture of my life !!!!!

[@tusharkkumar3835]

This will be very very helpful for all the students of IIT aspirants hit like if my comment is good

[@learnforeignlangwithhuda7707]

After one year you have got a like on your comment. Say thanks

[@prateekarora4549]

like the way how you teach

[@bhavya5508]

amaing sir ! time machine :D hope some day someone creates it :D !!!!!!

[@shariqansari2880]

very nice explaination

[@AMRITA805]

Sir, isn't poynting vector S= E cross B/mu nod?

[@debanjanmondal6233]

sir, at 1:11:00 , momentum = energy/ velocity......that means momentum is inversely proportional to velocity ....if we increase velocity , momentum will decrease and vice versa...it seems little bit condraticting to me...i must be wrong somewhere...sir please clear....

[@pragatimaurya2158]

very nice explanation

[@lostNseeker]

sir as the distances between the charge particle increases , the electriectric field should decrease but in ur graph it increases..............

[@pushpajoshi2866]

Sir l have question ,Is the displacement current opposite direction to conduction current?

[@sainispain316]

Sir sound waves are cracking in video

[@Parameswar_Ghosal]

sir , it is true that changing magnetic field creates electric field but my question is why the direction of new electric field is opposite to the previous electric field ? What is the reason behind that ? sir , Please clear my doubt as soon as possible .... Thank you sir ........

[@ABHISHEKKUMAR-om6vx]

Because charge goes back side of each other due to velocity then direction of field will apposite...

[@jagadishdutta5120]

According to lenzs law

[@kuldeepnegi9869]

See LC oscillations

[@ABHISHEKKUMAR-om6vx]

Sir I have a question.when electronic field lines reach max during vibration then velocity will zero at that ponit then B field will zero....I,e.at max Electronic lines magnetic field minm....but in this video in graph at max E and also B max.... please understand me sir

[@nikharjain]

Sir it means that peoples considering sound waves coming from space as signals from aliens are wrong..... PROBABLY, those waves are ours that are somehow reflected back to us with same frequency ? :)

[@bhavya5508]

:D

[@kajalesanjay4119]

yes . true

[@AlphaIntelligence1]

Sir will you please upload the videos of iit level numericals of these chapters!

[@krishnajha3606]

pehle base samjho uske baad IIT level ka numerical puchna

[@renumittal2098]

Sir Kya electromagnetic Waves ki frequency change hoti hai

[@kajalesanjay4119]

Renu Mittal ek particular emw ki frequency fixed rehti ha . like gamma rays and radio waves have different frequencies but have fixed with their own respect.

[@targetcompetitiveexams8903]

Thanku Sir 😊

[@tusharkkumar3835]

Sir please upload HC Verma video solution of a chapter please share mainly important exercise question

[@mtalhashahzad899]

sir how electric wave move if the is stationary?

[@kajalesanjay4119]

Talha shahzad change electric wave creates magnetic wave which also changes . and we have seen in earlier lecture that change in magnetic field /waves creates electric waves .

[@redflower4493]

No sound

[@pinkikiduniya2697]

pura hindi mai bhi banaiye

[@kahkeshanziya8905]

Nice sir

[@manjotdhaliwal4311]

There is a problem in sond

[@Laralappawedslulol]

there in no voice in this video !

[@nihaafzal6463]

ur head phones are broken .. :p

[@nikharjain]

+Manisha Dagar Frequency is less than 20Hz then :P

[@Laralappawedslulol]

yeah but my headphones had some problem which is now fixed :)

[@Laralappawedslulol]

yeah but my headphones had some problem which is now fixed :)

[@Laralappawedslulol]

yeah but my headphones had some problem which is now fixed 😃

[@MashukKhanScience]

The frequency of sound here is less than 20Hz maybe... It is unable to hear it....!!!

[@AnubhavSingh259]

+Mashuk Khan lol:P

[@MashukKhanScience]

+Anubhav Singh sorry between 20 to 20000 Hz...... Now it makes sense.....
