Zero Point Energy | Virtual Particles | Bohr Radius | Spectral Width | Nuclear Electron

We can use the Uncertainty Principle to predict some bizarre consequences on Quantum Physics - namely Zero point energy, non-existence of electrons in a nucleus, spectral width, calculation of Bohr radius, and existence of virtual particles.

The uncertainty principle in quantum mechanics states that it is impossible to simultaneously precisely know both the position and momentum (velocity times mass) of a particle; the more precisely one property is known, the less precisely the other can be known.

In this video, I discuss 5 consequences of the Uncertainty Principle in Quantum Mechanics.

I am eagerly waiting for this thanks a lot.

[freakingphysicist]

Man, you're my hero... I wanna become a physics teacher like you <3

[nevilpat]

BEST TEACHER SO FAR!!! LOTS OF INFO IN ADDITION TO NORMAL LECTURES!!

[wilayatreshi]

one the the best physics teacher i have ever seen..thanks a lot sir❤

[amankumarawasthi]

Sir pls make complete lecture on Schrodinger wave machanics.

[JohnnyRad]

Is a simpler explanation of Zero Point Energy basically that if a particle has mass, then there is a minimum finite value of energy it will still have at zero point energy?

[rahmatealam]

I am very excited to upcoming basic quantum mechanics video .your teaching style is uncredible ❤

[ihsanullah]

Hello sir, I'm from pakistan and i really like your videos, Your lectures clear my concept please make the remaing lectures because after 3 week my exam get start...

[GabrielOliveira-mkqd]

Hello professor, great video! I am seeing that a lot of these results depends on the fact that the value of a variable is always greater than or equal to the uncertainty associated with that variable, could you elaborate on why would that be the case? I see that otherwise the uncertainty would possibilitate negative values but why would that be a problem for, for example, the position of a particle, a value that can realistic achieve negative values.

[physicistkarthikeyan]

Pls upload more videos on quantum mechanics ❤❤❤❤

[surajyadav]

Sir thanks a lot!
All i know of QM is just bcz of u sir..
I am totally dependent on your videos
Just a question : Could you complete this course till 20 nov
(If not please tell how much it be covered till then🙏)

[amritasharma]

Thank you so much for the video sir but I think you might have forgot to attach pdf notes in description..

Sir, (h cut) = h/2π... so in uncertainty also it should
(h cut) /2.
But for derivation you have used h cut only.

I wish you mentioned this uncertainty is due to quantum fluctuation.

[lafenelson]

Awesome video, but it's still wild to me that you can get rid of a factor of 2 in the denominator and end up with the right answer.

I'm assuming it's the right answer and something is just going over my head.

Does the lifespan of 10 ns mean that is the length (in time) of the photon wave packet?

[worshipgod]

Sir I have this one question related to the displacement of a body when force is applied on it.
So the question goes like this :-
There is a boy travelling with a cycle and while travelling he throws a ball in upward direction (against gravity) but at the same time when boy is throwing ball he is also cycling due to which it happens that, the position of the boy when he threw the ball and the position of the boy when he caught the ball was different. The position in which the ball is caught is slightly ahead of the position in which the ball is thrown and the positions of both are different. Now basically when the position of the boy (along the cycle) has been displaced or it has been recoiled and then when we are applying force to the ball in a particular direction (meaning upward) then why is the ball back in our hands?Since we have already recoiled. So does it mean that the force we are applying is causing the displacement of ball in two directions, one towards the upward direction and one towards the direction in which boy is cycling.
Sir it could be a weird question for you but as a 10th grader I'm struggling in it. Maybe I haven't clear my motion basics. It would be very much helpful if you answered it
