Question

Which of the following are the observations made in photoelectric effect: (A) there is a minimum frequency below which no photoelectrons are emitted (B) the maximum kinetic energy of the photoelectrons depends only on the frequency of light and not on its intensity (C) no of photo electrons emitted depend on the intensity of incident light (D) electric charge of the photoelectrons is quantized​

Answer 1

Answer:

When experiments were performed to look at the effect of light amplitude and frequency, the following results were observed: The kinetic energy of photoelectrons increases with light frequency. Electric current remains constant as light frequency increases. Electric current increases with light amplitude.
