Question

Write the main features of photoelectric effect

Answer 1

Explanation:

Key Features of the Photoelectric Effect

The rate at which photoelectrons are ejected is directly proportional to the intensity of the incident light, for a given frequency of incident radiation and metal. The time between the incidence and emission of a photoelectron is very small, less than 10^–9 second.

Answer 2

Explanation:

Feature are:

i) For a given metal and frequency of incident radiation the number of photoelectrons ejected per second is directly proportional to the intensity of incident radiation .

ii) The maximum kinetic energy of emitted photoelectrons is independent of the intensity of incident radiation .
