Two adjacent energy levels of an electron in a harmonic potential well are known to be 1.10 eV and 1.54 eV .
What is the spring constant of the potential well?
Homework Answers
En = ( n+1/2)ħω
adjacent energy levels difference = En+1 -En = ħω
ħω = 1.54-1.10 = 0.44 ev
ω = 0.44/ħ = 0.44/ 6.5821 × 10-16eV s
=6.68479665e14
ω = sqrt(k/m)
k = m*ω2 = 9.1*10^-31*(6.68479665e14 )^2 = 0.4066472 N/m
spring constant of the potential well = 0.4066472 N/m
