Question

The scientist most often credited with the idea that a quantum of light (photon) can act as a particle is:

a. Schrödinger
b. de Broglie
c. Einstein
d. Heisenberg

Answer 1

C.) It was Einstein who created quantum of light

Answer 2

c. Einstein

Step-by-step explanation:

Einstein is most credited with the idea that a quantum of light (photon) can act as a particle. He proposed that light behave as photons or quantum of energy and used it to explain the Photoelectric Effect for which he received the Noble prize. Prior to that light was believed to behave as a wave or electromagnetic radiation only. However, photoelectric effect showed that light has particle nature as well.
