Understanding the wave particle duality using problem
An electron of energy 200 eV is passed through a circular hole of radius 10^-4 cm. Find the uncertainty introduced in the angle of emergence? What would be the corresponding uncertainty for a 0.1 g lead ball thrown with a velocity 10^3 cm/s through a hole of 1 cm radius?
Understanding the wave particle duality using problem
Consider a Gaussian wave packet given by Psi(r)=(1/r) exp(i k.r) where,r=(x^2+y^2+z^2)^(1/2). Calculate the probabilistic current density and interpret the result physically.
List the spectroscopic states (energy levels in the usual notation (2S+1)^L, that can arise from: one particle with S=1/2,L=3 one particle with S=2,L=1 two particles with s1=1/2,s2=1,L=4 two particles with s1=1,s2=1, L=3 two particles with s1=1/2,s2=1/2,L=2 Which of the two particles are excluded if the p ...continues
Materials exam study help/Request for 3 to 5 potential well problems worked out.
I have an exam tomorrow in my materials and devices class and am trying get more experience working potential well problems. The text for the class is Neamen - Semiconductor Physics and devices. I'd like to get 3 to 5 worked out problems involving the use of schroedinger's equation (position dependant - not involving time ...continues

If |0> and |1> denote the two eigenstates of N corresponding to the eigenvalues 0 and 1, respectively, show that c† |0> = |1> and c |0> = 0
Find the unitary transformation which transforms into a diagonal matrix and verify that the diagonal elements are 0 , 3, and 3
A 1000 newton crate is being pushed across a level floor at a constant speed by a force of 300 newtons at an angle of 20 degrees below the horizontal A-what is the coeffecient of kinetic friction between the crate and the floor. B-if the 300 newton force is instead of pulling the block at an angle of 20 degrees above the hori ...continues
