Quantum Mechanics Answers

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!

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.

A quantum particle confined to one dimensional box of width ‘a’ is in its first exited stated. What is the probability of finding the particle over an interval of ( a/2) marked symmetrically at the centre of the box.

A particle describes the curve rⁿ = αⁿcosnθ under a force p towards the ploe. Find the law of force.

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
