An atom in a state with its orbital quantum number l = 1 decays to its ground state (with l = 0). A photon of wavelength 630.000 nm is emitted in the process.
When the same process takes place in the presence of an intense magnetic field, the following change in the spectrum is observed. With the magnetic field present, one of the emitted lines observed now has a wavelength of 630.030 nm. Which of the following wavelengths would you expect to be also present?
A) 630.060 nm
B) 629.970 nm
C) 630.090 nm
D) 629.910 nm
E) 630.120 nm

B)

C)
It decreases.
D)
It may increase or decrease, depending on the shape of the rock.
E)
It may increase or decrease, depending on the weight of the rock.
