Question

what are the basic characteristics of photoelectric effect.?
​

Answer 1

Explanation:

The photoelectric effect has three important characteristics that cannot be explained by classical physics: (1) the absence of a lag time, (2) the independence of the kinetic energy of photoelectrons on the intensity of incident radiation, and (3) the presence of a cut-off frequency.

Answer 2

Characteristics of photoelectric effect

a) There is no time lag between the striking of light beam and the ejection of electrons from the metal.

b) The number of electrons ejected is proportional to the intensity or brightness of light.

c) The kinetic energy of the ejected electrons id directly porpotional to the frequency of the light used.
