[@deepikasharma3504]

Sir, besttttttttttt explaination of the world..... Nobody in the world like you also my school teacher... And I want to meet you once in my life.... You are my inspiration

[@shurtipandit5040]

I have no words to say , you are legend thank you very much👏👏

[@anmoldhawan3635]

I thing physics viva question ke liye 'physics vital 777'channel accha h .theory k liye pradeep sir ka channel best

[@ashusingh8911]

Sir nobody is comparable with u

[@qadshah1]

Sir please please upload college level physics video lectures in hindi english mixed language

[@sarveshsharma6892]

yes he is right

[@anushkapandey1366]

Sir you made me love physics.

[@ashusingh8911]

Sir u r amazingly very very brilliant teacher of physics

[@TriptoPal]

Awesome Explanation!!

[@georgejohny4800]

sir sound waves are also in waves, light waves are also in waves but ,velocity of sound increase in change in medium but light waves does exactly opposite how? Why?

[@georgejohny4800]

sir please reply

[@j.origamitutorials8216]

Sound is a mechanical wave and travels by compression and rarefaction of the medium. Its velocity in an elastic medium is proportional to the square root of Tension in the medium. A higher density leads to more elasticity in the medium and hence the ease by which compression and rarefaction can take place. This way the velocity of sound increases by increase in density. Light on the other hand is a transverse electromagnetic wave. It does not depend on the elastic property of the medium in which it travels. Its velocity in a medium is determined by the electromagnetic (e.g. dielectric) properties of the medium. Effective path length on the other hand is increased by an increase in the density and hence it leads to higher refractive index and lower velocity.

[@georgejohny4800]

thank you

[@anush7386]

George Johny yooo dude you are be a scientist

[@flawfulpractice8381]

good question

[@ece49salonijain30]

thank u so much sir for giving very simple and clear explanation

[@sudarshankulkarni6]

Awesome awesome explanation sir... the God Of Physics 🙏🏻🙏🏻🙏🏻😃😃😃

[@samarthgoel8904]

sir you are doing great work ... better explaination of every thing... thank you sir

[@alokparihar4241]

you are nice teacher ,,,,,,,,,,,,...............thanks sir...............

[@joshijoshi5669]

wow its really a great work sir plz add more and more lec every things get better explanation

[@ddboss847]

could it be that there is some vortex propogation ?? i mean an optical vortex ??

[@zohikhan5053]

Mr You are a brilliant teacher. Respect from Pakistan .

[@शिवमसिंहसिंगरौरप्रयागराज]

Hi zohi

[@ShayriHaan]

sir when will you upload other lectures

[@enamarora2941]

Sir always give unbeatable explanations ... Thnkue so much sir..

[@anmoldhawan3635]

I thing physics viva question ke liye 'physics vital 777'channel accha h theory k liye pradeep sir ka channel best.channel search karo kyonki sir bole h ki pichhli video chalne par hi nayi upload karege.video helpful h.check kajiye

[@amikasehrawat74]

Sir , what actually is meant by longitudinal wave ????

[@yuvrajroman1388]

Amika Sehrawat a straight uniform wave which goes straight with 0° angle

[@nikitajangid115]

Amika Sehrawat Longitudinal waves are the waves which vibrate in the direction of propagation of light.

[@rajataryan7166]

sir jab wave theory sab explain kar de to Ray optics Kyu padhte h

[@prashantsharma6954]

You are the best sir.

[@Rajveerpratapsingh3755]

[@mrs.sah1975]

Thankyou so much sir❤️❤️😇😊

[@srushtikadam2156]

When a wave enters a different medium, it's velocity changes and hence wavelength right? Is there any change in it's amplitude too?

[@varunkumar7237]

Amplitude of a wave gradually decreases after the wave is propogated and the phenomenon is called damping .

[@srushtikadam2156]

Let's talk theoretically and not practically.

[@varunkumar7237]

well then - amplitude , velocity etc do change on refraction www.physicsforums.com/threads/amplitude-change-of-light-during-refraction.308824/

[@jyotirai9931]

great sir may you live long

[@arkabhattacharjee3386]

Accelerated charge is the cause of EMW . What is the actual cause of light wave?

[@diplomat3565]

Light wave is also emf wave

[@abhishekanand8018]

or agar light em wave hai to ye compass ko deflect ku nahi karti

[@pt.madhugautam1846]

sir what is compton effect

[@eshwaabdullah9414]

Sir Koon se book use kar rahy hain??? Book ka naam bata dein

[@rakeshsahoo7311]

Thanks sir.....👏👏👏👏

[@theeetax6747]

highly appreciable can i get notes for xi and xii????

[@KuldeepSingh-hk8kp]

sirji, does the intensity of wave decrease with respect to distance?

[@sarby6560]

yes

[@abhishekanand8018]

sir,agar ek particle rest me hai to vo electric wave banega agar ek bar electric wave ban gai to magnetic wave bhi ban jayegi to iska matlab ye uha ki hame ek asa source mil gya hai jo infinite energy deta hai jo rest me ho its possible plzzzz tell me,....

[@vaibhavtripathi1774]

Technical sheky changing electric field causes magnetic field and changing electric field is caused by moving charge

[@abhishekanand8018]

Vaibhav Tripathi thanku

[@rudraanim.k9745]

Hello sir.. I have question.. we use a electric bulb for light purpose ..here electrical energy convert into light energy.... It means the light bulb emits energy pockets or photons as a result we lost electricity .... where do the energy or the photons go..?

[@kgnstarinterior2118]

photons get destroy after striking a surface

[@anmoldhawan3635]

I thing physics viva question ke liye 'physics vital 777'channel accha h. theory k liye pradeep sir ka channel best

[@anmoldhawan3635]

Light energy is absorbed by other objects and converted into heat

[@harendrakumar8548]

sir how much do u earn a month

[@ManishSharma-bw8mm]

Sir ur sound is not clear pls work on it

[@pawanmeena4399]

sir question of George Johnny is very good sir please answer that

Please do question

[@rudraanim.k9745]

Answer plzz sir..

[@vitthalramtakke5421]

is this CBSE or state board

[@Girl_With_Specs]

Vitthal Ramtakke I think heteaches from state board book of physics..

sir your videos are too much lengthy I sometimes get bore. plez try to make video of least 20 min.

[@cookwithvrata3349]

+Pradeep Kshetrapal sir you don't need to . you explain every single thing and thats awesome . I attend aakash classses but our teacher is not good but your videos are very helpful .

[@jagratishrivastav273]

Sangeeta Bajaj Well I've find the another way for my convenience, I set videos to 1.5x speed.

[@pincessofpokeworld]

I watch at 1.5x because sir speaks slow so that helps

[@muskanmishra3509]

jagrati Shrivastav thanx for the idea..😊

[@bella.s8132]

what is locus ?

[@kamalajacob7141]

bella .S locus means Path

[@yuvrajroman1388]

Locus is a curved path..which is perpendicural to the secondary source

[@akankshaagrahari4874]

Thank you sir
