An Electron Is Bound in an Infinite Well (A Box)

question 40

Short Answer

An electron is bound in an infinite well (a box) of width 0.10 nm. If the electron is initially in the n = 8 state and falls to the n = 7 state, find the wavelength of the emitted photon. (c = 3.00 × 10⁸ m/s, h = 6.626 × 10^-34 J ∙ s, mel = 9.11 × 10^-31 kg)
