Explanation The photoelectric effect is based on the fact that metals emit electrons when they come in contact with light. Moreover, the photoelectric effect depicts the particle nature of light. There is no change in the threshold frequency with the increase in intensity of light. To explain this behavior, Einstein deduced an expression in 1905, which is as follows: E = h υ Since υ = c /
