Homework Statement
(Please look at the attached file too)
In one dimension time independent potential well, I want to know what is a suitable unit for energy (electron volts or joule)
Homework Equations
The Attempt at a Solution
In the attached picture, I've tried to analyze each variable's unit. I did this in two cases:
1) when I substitute energy terms in eV
2) when I'm doing so in joule
I substituted units into Schrodinger's Equation and I got 1=1 when I plugged energy with joule. (Please look at the bottom of the attachment)
After I've done this, I thought that the SI unit should be used so energy should be in joule. I plugged all available value in the equation but constants (coefficients) in the equation went crazy! Instead, energy in electron volt gave me much simpler equation to solve.
Thank you
