Which one of the following statement is not a part of the quantum theory of light? (1) There is a minimum frequency of light below which no photoelectrons are emitted.(2) The maximum kinetic energy of photoelectron depends only on the frequency of light and not on the intensity.(3) Photoemission occurs when light of appropriate frequency but minimum intensity is incident.(4) The charge of photoelectrons is quantized |

Answer» Correct option : (4) Explanation: Option (1), (2) and (3) are experimentally observed facts of the phenomenon of photoelectricity and are explained by Einstein’s theory of the photoelectricity. Option (4) refers to quantization of charge in general and is not a part of Einstein’s theory of photoelectric emission. |
