Thank you for answer on my question "Quantum Mechanics Question #3422" about the amplitude of electron. If I may ask another question: What is the quantum constant and how did they manage to measure it? Can we say that quantum constant is the smallest amount of energy to move something? Is there any relation between gravitational constant and quantum constant? Thank you very much!

A laser delivers pulses of 2mJ at wavelength 633 nm with a pulse duration of 200 ps.
(hint E=h.c/l, with h=6.6 x10-34 J.s and c=3x108 m/s and 1 eV=1.6 x10-19 J)
i) How far do they travel in 1s?
ii) What is the photon energy in eV?
iii) How many photons are delivered per pulse?
& please show working out

I would be very grateful to you if you could answer me if electron has an amplitude? I don't mean probabilities of finding an electron. I mean if an electron does have, beside frequency and wavelength also an amplitude.Thank you very much!

So, in Quantum Entanglement ....when discussing atoms can we say that if two atoms simply touch they will become entangled? Or is there a more complex process which forces them be become entangled.
What is the simplest way atoms can become entangled.
Also can just proximity ...that is atoms that are close to one another become entangled because their vibration effects entanglement? Thanks so much.....jw

Hey,
I just want to know that
Is kinetic energy conserved in Compton effect?
I know that TOTAL ENERGY and MOMENTUM is conserved.
Thanks

A quantum particle is moving in a harmonic oscillator potential v(x)=m*omega^(2)*x^(2)/2.
The eigenstates are denoted by |n> while the wave functions are Psi n (x) = <x|n>.
At t=0, the system in the state: |Psi(t=0)>=A*sum from n of (1/sqrt(2))^2 | n >
Find the constant A, obtain the expression for the wave function Psi(x,t) = <x | Psi(t)> at a latter time, calculate the probability density |Psi(x,t)|^2 and the expectation value of the energy.

Can mass be measured in the absence of force (4 fundemental forces)? in complete isolation can a mass of an object be determined?
if yes how?
if not... then how can we define that the object even exists in absolute isolation ?
thank you
