Question

The incidents light has intensity I and the number of electrons emitted per second is N. Then the maximum kinetic energy of emitted electrons per second is K. If the intensity of the incidents light is doubled, then the number of electrons emitted per second and the maximum kinetic energy respectively are (A) N , K (B) 2N and K (C) N and 2K (D) 2N and 2K

Tardigrade Admin · Accepted Answer

The maximum kinetic energy of emitted electrons is independent of intensity of incident light and the number of electrons emitted directly proportional to the intensity of incident light

$N, K$

$2 N$ and $K$

$N$ and $2 K$

$2 N$ and $2 K$

The maximum kinetic energy of emitted electrons is independent of intensity of incident light and the number of electrons emitted directly proportional to the intensity of incident light
