The diagram represents the precession of an atomic nucleus in an applied uniform magnetic field.
Which label represents the spin of the nucleus?
Which label represents the applied magnetic field?
Which label represents the precession of the nucleus?
An atomic nucleus is in a uniform magnetic field, as shown in the diagram. The nucleus absorbs a photon that has a frequency equal to the precession frequency of the nucleus. Which of the following diagrams most correctly represents the nucleus just after it absorbs the photon?
The diagram shows the spins of some atomic nuclei before and after a uniform magnetic field is applied to them. Which of the following correctly describes the effect of the magnetic field on the nuclei?
