In what year did Albert Einstein receive the Nobel Prize in Physics?

• A. 1915
• B. 1921
• C. 1939
• D. 1955

Answer: (B)

Albert Einstein was awarded the Nobel Prize in Physics in 1921, primarily for his discovery of the photoelectric effect, a phenomenon that is central to quantum theory. This award represented a significant recognition of his contributions to theoretical physics, particularly at a time when much of his more revolutionary ideas, like the theory of relativity, were still being heavily debated and not universally accepted. His work on the photoelectric effect demonstrated how light could exhibit both wave-like and particle-like properties, which was pivotal in understanding the dual nature of light and laid foundational work for modern physics. The other years mentioned are significant in Einstein's life and contributions but do not correspond to the time he received the Nobel Prize. 1915 was when he published his general theory of relativity, while 1939 and 1955 are years associated with other aspects of his career and life events, respectively.
