-
Hhokhani replied to the thread High School Photoelectric and summation of photons energy.If I understood correctly, you mean that intensity is independent of frequency. Isn't it?
-
Hhokhani posted the thread High School Photoelectric and summation of photons energy in Quantum Physics.Classical electromagnetic field can't explain photoelectric effect since at any frequency, increasing the intensity only increases the...
-
Hhokhani posted the thread Undergrad 2D rotation and angular momentum uncertainty in Quantum Physics.In quantum mechanics, the uncertainty among the components of the angular momentum doesn't allow to find all the components together...

Hhokhani reacted to Chestermiller's post in the thread High School Internal energy and gravitation with
Like.
The more general form of the 1st law of thermodynamics is $$\Delta U+\Delta (PE)+\Delta (KE)=Q-W$$where PE is the gravitational... -
Hhokhani replied to the thread High School Electron absorbs photon, but what happens to the photon?.Is this wave function calculated by Hamiltonian?

Hhokhani reacted to gyorgiy's post in the thread High School Internal energy and gravitation with Like.
The crucial word in this context is "internal". If you include interactions with external objects, it no longer differs from total...
-
Hhokhani replied to the thread High School Internal energy and gravitation.Yes. Thanks all. Your comments resolved the ambiguity about internal energy and potential energy.

Hhokhani reacted to Herman Trivilino's post in the thread High School Internal energy and gravitation with Like.
You need at least two objects (usually modeled as particles) interacting with each other (via a conservative force) to have potential...

Hhokhani reacted to PeroK's post in the thread High School Electron absorbs photon, but what happens to the photon? with Like.
In QFT (Quantum Field Theory) photons are described by the quantized EM field. Or, perhaps it's better to say that the Quantum Field...

Hhokhani replied to the thread High School Electron absorbs photon, but what happens to the photon?.Does photon have wave function?
-
Hhokhani replied to the thread High School Internal energy and gravitation.The potential by its own is not physicaly meaningful and it is the potential difference which is important. We can choose any point as...

HWhen a mass M and a much smaller mass m, are released to fall towards eachother, then in the common center of mass frame, the...

Potential energy of one object is indeed zero. I agree with that but don't understand what you mean by an origin or by "another point"...

Hhokhani reacted to Andrew Mason's post in the thread High School Internal energy and gravitation with Like.
The internal energy is a thermodynamic property of a system and it is a function of its thermodynamic state. If the work done on the...

Hhokhani replied to the thread High School Internal energy and gravitation.Usually in elementary physics text book, dealing with energy concept is in such a way that we first choose a reference frame for kinetic...
