(ii) A silicon detector contains a photoconductive layer of thickness 1 = 20mm. The refractive index of silicon is 4 and the absorption coefficient (a) of silicon in cm-1 is given by a = 10(7-6000) where I is wavelength in Å. Calculate the wavelength at which the quantum efficiency loss due to penetration through the device is equal to that due to re- flection at the surface.
(b) A photon is emitted by a doubly ionised lithium atom (Li²+) when an electron makes a
transition to the ground state. The wavelength of the photon is measured to be 10.83
nanometres.
Determine the principal quantum number and the energy of the initial state
The atomic number of lithium is Z = 3.
(2) In this experiment, why couldn't we observe the series of spectral lines that arise from electrons
falling to the ground state, nfinal = 1? This is the Lyman series, for which 22 (see eq. (16)) must be
replaced by 12 in both the numerator and denominator of the equation: 2 =-
1 n2
n =
R (n2-1)'
