[@RoHIT-xv1lf]

Sit kal exam tHi or apke videos ne bohot help ki sir thanks you very much

[@anujtalwar]

life saver ho yaar bhaiya aap
kal paper hai mera aapke videos ne bacha liya bs mujhe

[@LifeWithShweTanvi]

You have explained it really well!😄

[@jsingh1349]

Nice video sir.... Great explanation!!

[@jsingh1349]

Sir it's great video ,please continue

[@tanuagarwal2617]

your explanation is good but i want optical resonator cavity in more detail......

[@adityaprasadkar3175]

Thnxx sir u have explained more easily than others... I understood it completely

[@suchitrakumari1925]

Thanks sir you are best in the world

[@somalajayesh8096]

Physics become easy for me by your vedios

[@abhishekrathore77]

Thanku so much sir very good explain very useful video keep it up sir ji

[@aliasif8398]

Fraunhoffer diffraction
at single slit and grating, Rayleigh’s criterion of resolution, resolving power of grating sir yeh topic samgha diye please

[@shubhamagrawal8059]

Helpful video sirji

[@rahulmehra6520]

too good 👌 👌

[@himanshurai1888]

Thanks for the video, helped a lot

[@SagarSingh-ob5jt]

Sir your videos are to the point and easily understandable......please make videos on Magnetostatics, Magnetostatics in linear magnetic medium and Faraday's Law.
It will be very helpful for everyone in this quarantine period!!!!
I hope for positive response.

[@subhransu7810]

so much thanks sir...you are a life saver

[@atishmurmu3418]

Thank you so much..... 🤗🤗🤗

[@srsrt6979]

Bohot help mila sir

[@usamagondal6387]

Thanks Sir .. From Lahore, Pakistan

[@AMANRAJ-zh4oj]

sir aap bahut achchha samjhate hai

[@dineshkarankot2369]

Its help full sir

[@keshavtyagi1928]

just brilliant...

[@knowledgehouse5193]

i have a doubt about population inversion. where they occure at highe excited state or metastable state

[@himanshumishra7203]

How could temperature be negative?
7:20

[@AbhishekSingh-nk5wb]

Thanks you sir very nice vidio

[@Amazing_Movie_Insights]

U r too gud man

[@surajborah7687]

Sir mention six basic requirement for the generation of laser

[@SureshKumar-pm1hd]

Thanks sir ji

[@dharampalsingh2975]

Thanks sir

[@SureshKumar-pm1hd]

Nice

[@somsuvragupta3025]

Can Temperature really be negative?

[@prakashiniagrahari3295]

thanks alot sir

[@AnkitKumar-pk8tk]

Sir can we excite electron directly to metastable state?

[@VivekKumar-vi6xd]

Not possible,,,for that we have to do spontaneous emission Which is only possible when atom is in exicted state and com,,,,then atom comes from exicted state to metastable state by cause of spontaneous emission

[@dheerendrasinghpanwar9900]

Good sir

[@wajahatnaeem1208]

Jabardast

[@dineshkarankot2369]

Tq sir

[@SatyamPandey-hi9mo]

sir aap page clear to show kigiye

[@NishadShimpi]

bro just scream less u are like so loud in the video that i need to keep the volume at 1

[@rambabusingh4989]

Sir PDF provide kijiye na

[@ENGINEERINGPHYSICS]

From this link you can download notes:-
sites.google.com/view/engineeringphysics111/notes

[@SonuKumar-wk9de]

Optical method not clear

[@ribhus6262]

Bad video coz you should discuss little details also such as discussing about process how optical resonator works.

[@shailesheng...kasyap7706]

Nice sir
