Photoelectric phenomena

Question 1

1

Answer 1

The electron get ejected from the metal they’re hit by individual photons

Question 2

2

Answer 2

The photons then transfers energy to the electron which is ejected from the metal. In this process the photon is destroyed

Question 3

3

Answer 3

However there’s a minimum energy that the photon needs to transfer in order to get the electron to overcome it’s attraction to the metal

Question 4

4

Answer 4

That minimum energy is called the work function energy

Question 5

5

Answer 5

If the photon has less energy than the work function then it won’t go anywhere

Question 6

6

Answer 6

But if the photon has more energy than the work function the some of the photons energy will be used up to tear the electron away from the metal and the rest will givee kinetic energy
