Question

why does the kinetic energy of the ejected electrons do not depend on the brightness of light? ​

Answer 1

Explanation:

it depends as the kinetic energy is transmitted to the body which it strikes and it becomes in light energy

Answer 2

Answer:

Electrons are ejected only when the frequency of the incident light is higher than a threshold value, fo, regardless of how intense the light is. The threshold frequency depends on the material being illuminated.
