Compute the wavelength, frequency and wavenumber of then n=4 ---> n=3 transition of Be3+

Determine the wavelength of the line in the hydrogen atomic emmission spectrum corrsponding to the ninitial=4 to nfinal=3 transition.

Calculate the energy difference between n=1 and n=2 levels for an electron confined to a onedimensional box having a length of 4.0 x 10-10 m. What wavelength corresponds to a spectral transition between these levels? (5)
