OT- Anyone a Physics Whiz?

If you are good at physics, can you PLEASE help me with these??? Suppose a particle of mass m is confined to a one dimensional box of width L. According to quantum theory, the particle's wave ( wavelength=h/mv) is a standing wave with nodes at the edges of the box. (a) show the possible modes of vibration on a diagram (similar to standing waves on a string). (b) show that the kinetic energy of the particle has quantized energies given by KE= n^2 H^2/ 8ml^2 (note ^2 = means to square) where n is an interger. (c) calculate the ground state energy (n=1) for an electron to a box of width 0.50x10^-10m. In X-Ray production, show that the cutoff wavelength initial 40nm/v where v is the X-Ray tube voltage. VAL

Well, I'm pretty sure I can't help you, but I'm feeling like a MASS of a ONE DIMENSIONAL math idiot who isn't on the same WAVELENGTH as someone with half a brain!

DINA, YOU STINKER! I LITERALLY LOOKED AT YOUR NEW PHOTO AND DID NOT KNOW WHO YOU WERE!!! Aw, you're gorgeous, sweetheart! No wonder you've got some major flirtations going' on -- if I were your husband I'd keep a net over you!!! Maureen

Duh... Well... I guess I didn't take enough B-12 for this one, but best of luck to you Val! Joy

I ducked my head deep in the sand when I read this post but am peeking out only long enough to ask ... why are you asking??? Reenie
