Question

If a proton emits a photon in a spin-flipping event in a magnetic field, which is true?

A. It flips from spin up to spin down.

B. It flips from spin down to the spin perpendicular to the magnetic field.

C. It flips from spin down to spin up.

D. It flips from spin up to the spin perpendicular to the magnetic field.

Answer 1

C.

Step-by-step explanation:

We know that the magnetic moment of electron is in same direction as it's spin so it's spin flip from down to up.

The correct answer is C that is . It flips from spin down to spin up.
