    Infinite Square Well Electron Jumps from n=4 to ground state

    Homework Statement An electron is trapped in an infinite square-well potential of width 0.5 nm. If the electron is initially in the n=4 state, what are the various photon energies that can be emitted as the electron jumps to the ground state?Homework Equations ΔE=13.6(1/nf2-1/ni2)...

    Find the Initial and Final states of an excited Hydrogen Atom

    Homework Statement A hydrogen atom in an excited state absorbs a photon of wavelength 434 nm. What were the initial and final states of the hydrogen atom? Homework Equations 1/λ=1/91.127 * (1/nf2-1/ni2) The Attempt at a Solution Tried to use the equation, but keeping the initial...

    Two explosions occur, spaceship is flying overhead at 0.6C, which occurs first?

    Thanks for moving the thread, sorry about that. I did all the math, but i still come up with the time for the denver explosion at 0 seconds and the aspen explosion at somehow a longer time of 0.000375s. Am I wrong in saying that the (x,t) coordinates of the denver boiler are (0,0) and aspen...

    Two explosions occur, spaceship is flying overhead at 0.6C, which occurs first?

    Homework Statement At 11h 0m 0.0000s AM a boiler explodes in the basement of the Denver Science Museum. At 11h 0m 0.0003s, a similar boiler explodes in the basement of a ski lodge in Aspen at a distance of 150 km from the first explosion. Show that in the reference frame of a spaceship moving...
