Thank you I really appreciate you for making these Lectures ,They are really helping me in my Learning I wish you and your family the best wishes. Mohamed
Thank you so much sir really helped me a lot ...kindly upload the lectures of physical electronics if possible or recommend anyother channel for physical electronics plus I saw you uploaded the lectures on quantum mechanics unfortunately we are not following that book the book our teacher I following is of nouredine zettli
Sir in the current case we are considering the box, why are we taking particularly a box ,why not other geometry? , can we take a sphere or cylinder in this case?
For a spherical geometry, we consider a spherical Gaussian surface, for cylindrical, a cylindrical Gaussian geometry and so for a plane geometry, a plane Gaussian surface. Although we can use other geometries but that will make our calculations very tough and almost impossible. This is like when we measure the length of a plane surface, we use a flat scale. In the same manner for measuring the circumference of a circle, we don't use a flat scale because that will make our calculations much tougher. Thanks
Great explanation sir,Take love from Bangladesh
Thanks and welcome dear. Please share it with your friends in Bangladesh. With live from Peshawar, Pakistan.

Thanks for the appreciation dear 😊. Sure, uploads will be continued soon IA. Thanks for sharing ☺️
Za the Karachi university na sir g! Der zabardast o mayaree lecture dy warpessee chaptero lectures hm upload kee no der ba khwee. Manana
Dera manana. Aw g, Noor chapters om zar ba upload Kam IA. Please share these lectures with your fellows and friends. Abaad osey

Very fruit full
Thanks dear

Thanks for the appreciation dear 😊. Whatever book is being followed, the content of QM is the same. N. Zettelli is focusing more on problems. Thanks 👍

@@SAYPhysics thank you sir for your response
❤❤❤❤
❤️
Please make videos on magnetism also
Sure dear. I'll cover rest of the whole book. Thanks
