Homework Statement Near a certain position xA, a quanton's wavefunction ψ(xA)=-0.3 in some units. Near a certain position xB, a quanton's wavefunction ψ(xB[\SUB])=0.12 in the same units. If we do an experiment to locate the quanton, how many times more likely is i that the result is in a small...

Yes, but do you have any idea what the process I used to change uncertainty in wavelength to uncertainty in frequency was? Something like: deltax=((x+deltax)-(x-deltax))/2

Thanks for your help. I have one more question for anyone who knows the answer. What's the method I used to find uncertainty in frequency? It is shown in the Excel file, but I can't remember what it's called.

Is there a way for me to give more weight to points with less error, or to account for error bars when calculating regression Excel?

Didn't know you could attach files! Here's the actual spreadsheet.

Homework Statement I'm trying to make sense of some data taken during a lab in which we were tasked with obtaining a value for Planck's constant by measuring different stopping voltages from varying wavelengths of light. The value I got was 3E-15 eV*s, but I know I can get a better value if I...
