Laser Adventure" Chapter 2.2 page 4
Question 2.1:
Is it allowed to calculate first the wavelength difference (l2-l1),
and then use the relation between frequency and wavelength (n2-n1)=
c/(l2-l1)
?
Question 2.2:
Calculate in units of Nanometer,
the wavelength of light emitted by the transition from energy level E3
to energy level E2 in a 3 level system in which:
E1 = 0 [eV]
E2 = 1.1 [eV]
E3 = 3.5 [eV]
