Photoelectric effect

Light of certain minimum frequncy can eject electrons from the surface of the metal, creating a measurable current at a nearby detector

2
New cards

As the intensity of light increases

the number of electrons emitted increases

3
New cards

As frequency of light (at threshold) increases

the kinetic energy of light increases

4
New cards

As intensity of light increases

the kinetic energy of electrons stays the same
