Homework Statement
A ruby laser emits light of wavelength 694.3 nm. If this light is due to the transition from n=2 to n=1 state of the electron in a box, what is the width of the box?
Homework Equations
K=2pi/Lambda
kL=npi
The Attempt at a Solution
Thinkin about the problem, i have calculated K as shown in my formula to be 9049669 but when i use this k to find L then i end up with 694.3 again. I don't know if this is the answer or if this is a really big mistake?
