Albert Einstein’s 1921 Nobel Prize in Physics was awarded specifically for his explanation of which phenomenon, rather than for his theory of relativity?

Explanation

Although Albert Einstein is most famously associated in popular culture with his theory of relativity, his 1921 Nobel Prize in Physics was specifically awarded for his theoretical explanation of the photoelectric effect, describing how light can behave as discrete packets of energy called photons. This work made significant contributions to the early development of quantum theory. Einstein’s theories of special and general relativity, while enormously influential, were still considered somewhat unproven or contested by parts of the scientific community at the time the prize was awarded.
