Question

Einstein’s work on photoelectric effect provided support for the equation

(a) E = hv

(b) E = mc²

(c) E = - Rhc / n²

(d) E.K = 1 / 2 mv²

Answer 1

Correct option: (a) E = hv

Explanation:

Einstein’s photoelectric effect & compton effect established particle nature of light. These effects can be explained only, when we assume that the light has particle nature (To explain, Interference & Diffraction the light must have wave nature. It means that light has both particle and wave nature, so it is called dual nature of light).
