Thank you sir very nice gide & very nice best explain density of states teaching video.👍

[@gautamvarde]

Thank you dear for your continuous support 💖

[@Krish_012]

Perfect explanation of this topic ✅

[@gautamvarde]

Glad you think so!

sir you are a great teacher hats off to your effort!!!

[@gautamvarde]

Thanks dear

[@motiurrahman900]

h is Planck's constant, not degree of freedom

[@GamingwithVishnuYT]

Yes

[@buggu1433]

Calculating volume=energy and then this energy becomes N(E)dE.....very confusing

[@NeelRaval-n9y]

You're an amazing teacher!!

[@Deepanshutyagi-q2m]

Sir your explanation meathod is very good

[@gautamvarde]

Thanks and welcome dear

[@Ncpedia]

perfect explanation👏.tq sir

[@gautamvarde]

You're most welcome dear

[@ganinitianelectricalkkr9686]

Yes sir I also found at very last moment simple silly mistake of 3/2 .
I was inventing this video last 2days.
But no one has explained like this
I was wanting this same to same derivation because of previous year question.
At last
Thanks sir.

Well come dear

good explanation sir 💝

Thanks and welcome

But the first 'n' is radius and the second 'n' is quantum number. How are you replacing them?

[@ALLINONE112]

Sir we have two topics in our syllabus which are
Density of states of continuous medium & Density of states of lattice, are they same or different.

[@ALLINONE112]

For Density of states of continuous medium i have derived the formula
g(E)=2πV/h^3 (2m)^3/2 E^1/2

[@sharstikadian]

Sir at last jo equation aati h usme 3/2 bhi lagega kya 8ma2/h2 k sath

[@gautamvarde]

Yes dear you are correct.
I missed to write 3/2 at last.

[@sharstikadian]

@@gautamvarde ohk sir

[@prabhatsharma9357]

Final expression main power kaha gaya,,chack it

[@AYUSHKUMAR-gb2sn]

3/2 hoga !!!
no tnsn

[@nishusingh8191]

But sir degree of freedom is f not h

[@vanshgujjar1075]

Why you take 1/8volume of sphere and why you put 1 below in D(3d)=NE(DE)/1?

[@sedbaka]

abe unpadh, usne bola toh octate le rahe hai sphere ka, means poora sphere consider nhi kr rahe hai , just the 1/8th part of it

[@thinkshigh6645]

Thanks sir❤

Nice😊

[@rylephoenix8002]

Sir how did you replace radius 'n' with quantum number 'n' ? Please explain sir. Thank you!

[@BharatThakor-bu8pq]

Do You know about radius replace in quantum number?

[@anirbandey6206]

No bro please say​@@BharatThakor-bu8pq

[@vanshgujjar1075]

You take N(E)DE/volume ,NEDE==1/8volume why????

[@Filmicampus]

Sir Everything is perfect But Your Board is very small. Clearly not visible. Black Board is perfect 🙏🙏

[@Amazing_Amit_Funny]

Sir ye a2 kya hai samjh na aaya kya bola aapne

[@hamzaravani6315]

Sir, pehle aap ne 'n' ko radius bola, aur volume find karke usko Energy se equate kar diya,
Bad me n²h²/8ma² vaale step me 'n' to quantum no. Hai na, to usko 'ndn' se equate kaise kar sakte hai ?
Plz explain sir, I'm confused,
Thank you

[@gautamvarde]

Dear Hamza, kindly repeat the video, you will get clear that point.
Thank you dear

[@nickyvance8193]

Mera bhi same doubt hai ....tumhara clear hua kya

[@motiurrahman900]

E=n^2 h^2/8ma^2 or n^2= 8ma^2/h^2 E differentiate it you will get

Sir aap notes ki pdf bhi send kar dijiye jis se ham sabhi baccho ko help mile 🙏🙏

[@rushabhbhanushali8332]

Sir at last 3/2 is missing . Isn't it?

[@gautamvarde]

Yes dear.
My mistake, apologize for this.
3/2 I forgot to write.
Thank you.

Sir z(E) dE last equation me rais to 3/2 nahi he!!

Yes dear Virtual you are right.

Sir last me power 3/2 hoga chhut gya hai

Yes dear

Sir explain E=n²h²/8ma²

[@ManojKumar-cj7oj]

E= p^2/2m , put p=hk/2pi and k= n.pi / a (its the solution for infinite sqr well potential)
