This is how I went about it but I am unsure if it is correct..
An n=3 to n=1 transition from an electron trapped in a rigid box produces a 240 nm photon. What is the width of the box?
λ = hc / E:
E = hc / λ
E = (1.06E-34 J*s * 3E8m/s) / 240nm
= 1.33E-19 J
E = h2 / 8mL2
L2 = h2 / 8mE
L = √ h2 / 8mE
L = √ ((1.06E-34 J*s) 2 / (8*9.11E-31kg*1.33E-19 J))
= 1.08E-10 m
