This video is about the photoelectric effect. After watching this video you will be able to:
- Know that the photoelectric effect refers to the phenomenon in which electrons are emitted from the surface of a metal when light strikes it.
- Know that the photoelectric effect studies in which the frequency of the light is varied show that no electrons are emitted by a given metal below a specific threshold frequency.
- Understand that for light with frequency lower than the threshold frequency, no electrons are emitted regardless of the intensity of the light.
- Understand that for light with frequency greater than the threshold frequency, the number of electrons emitted increases with the intensity of the light.
- Understand that for light with frequency greater than the threshold frequency, the kinetic energy of the emitted electrons increases linearly with the frequency of the light.
