Question

The photoelectric effect: a. describes the phenomenon of producing light by shining a beam of electrons on a metal surface until it glows. b. was explained by Max Planck. c. is the phenomenon that electrons will only be ejected from the surface of a metal by light that has some minimum brightness, no matter what the frequency. d. is the phenomenon that electrons will only be ejected from the surface of a metal by light that has some minimum frequency, no matter how bright or how long you apply the light at a lower frequency. e. results in the ejection of electrons by light at high intensity.

Explanation / Answer

Photoelectric effect is phenomenon of ejection of electron only under the condition if the frequency of light is more than a threshold frequency . It is irrespective of the intensity of Light whether bright or dim . Photoelectrons are electrons are ejected as a result of this interaction
