Question

Intensity of light depends upon​

Answer 1

Explanation:

Each packet or photon could cause one electron to be ejected, which is like having a moving particle collide with and transfer energy to a stationary particle. The number of electrons ejected therefore depends upon the number of photons, i.e. the intensity of the light

Answer 2

Answer:

The intensity of light s defined as power per unit area, and power is defined as energy per unit time. Thus: I=PA=EΔt1A.

Explanation:

so it depends on POWER ,AREA
