The Einstein-de Haas experiment showed that:
A)atoms emit and absorb light, but only of certain wavelengths.
B)atoms have momentum, and momentum is conserved.
C)atoms have electric fields, and electric fields can cause their energy levels to split.
D)atoms have magnetic dipole moments that are coupled to their angular momentum.
E)a gradient in a magnetic field will cause a beam of atoms to split.

Question

Quizplus · Accepted Answer

The Einstein-de Haas experiment demonstrated the coupling of the magnetic dipole moment of atoms to their angular momentum, showing that the application of an external magnetic field can cause a macroscopic object (in this case, a suspended iron rod) to rotate due to the reorientation of the individual atomic magnetic moments. Options A, B, C, and E do not apply to this experiment.
