Solution
(d) Einstein successfully explained the photoelectric effect using the assumption $E= hv.$ This assumption is given by Planck. Einstein showed that not only light is quantized but also atomic vibrations are quantized. He was able to explain this result by assuming that the oscillations of atoms are quantized according to $E=$ $n h \nu$
