- The emission of photoelectrons is instantaneous.
- The number of photoelectrons emitted per second is proportional to the intensity of the given incident light.
- The maximum velocity with which electrons emerge is dependent solely on there frequency and not on the intensity of the incident light.
- There is always a lower limit of frequency called threshold frequency below which no emission takes place, however high the intensity of the radiation may be.
