Homework Statement When a hydrogen atom undergoes a transition from the n=2 state to the n=1 level, a photon with \lambda=122nm is emitted. a)If the atom is modeled as an electron in a one-dimensional box, what is the width of the box in order for the n=2 to n=1 transition to correspond...

Thank you for your help, I am not sure if I'm on the right track but I used the kinetic energy formula to find velocity then I used that velocity in the lambda=h/mv formula to find the wavelength, is that right?

Homework Statement Find the uncertainty in the momentum(in kg x m/s) of an electron if the uncertainty in its position is equal to 3.4x10-10m, the circumference of the first Bohr Orbit. Homework Equations n\lambda=2r \lambda= h/mv mvr= nh/2\pi The Attempt at a Solution 3.4x10-10=2 pi r...

Homework Statement Microscopes are inherently limited by the wavelength of the light used. How much smaller (in order of magnitude) can we "see" using an electron microscope whose electrons have been accelerated through a potential difference of 50,000V than using red light(500nm)...
