Question

Question 32 All of the following results of the photoelectric experiment violate the expectations from the wave theory of light EXCEPT: A. The emission of electrons from the target plate under dim blue light but not under bright red light O B. The instantaneous emission ofelectrons from the target plate upon applying a dim green light. ° C. The emission of more electrons from the target plate under bright green light than under dim green light. O D. The emission of higher energy electrons from the target plate under dim blue light than under bright green light.

Explanation / Answer

The correct option is B. the instantaneous emission of electrons from the target plate upon applying a dim green light.

The property mentioned in option B shows the particle nature of light or deviation from wave theory of light. This shows that the dim green light contains enough energy to emit the electrons instantaneously from the target plate. The number of emitted electrons will be proportional to the intensity of light.
