Question

Why is photoelectric current proportional to intensity?

Answer 1

Here is your answer ⤵⤵⤵⤵⤵

It's because intensity is directlyproportional to number of photon in light ray and in photoelectric effect one photon can only release one electron and so more intense light means more photon hence more elections will ejected from the metal surface and hence increasing the photo current .

Answer 2

Due to intensity is directly proportional to number of photon in light ray and in photoelectric effect one photon can only release one electron and so more intense light means more photon hence more elections will ejected from the metal surface and hence increasing the photo current .
