Homework Statement
An electron confined in an infinite well (1 dimensional) can absorb a photon with a maximum wavelength of 1520 nm, what is the length of the well?
Homework Equations
λ=2L/n
E = hf (photon)
E = n^2*h^2/8*m*L^2
The Attempt at a Solution
I honestly don't know what to start with, I solved for the energy of the 1520 nm photon, but I'm not sure what that tells me. Also the fact that this is the maximum wavelength that the electron can absorb is supposed to tell me something which I'm not entirely sure what. I looked around and read my textbook many times but I'm still not sure. Any hint would be great, thanks.
EDIT: I should add, this is a first year physics course intro to quantum mechanics chapters
