Write the experimental observations of photo electric effect.

1.	Write the experimental observations of photo electric effect.
Answer» The following one the other experimental results of photoelectric effect: 1. Photoelectric effect is an instantaneous process. 2. The minimum frequency is required to remove the electron from the metal surface is called threshold frequency. If the frequency of incident light is less than threshold frequency them their is no photoeletric effect. 3. The minimum energy required to remove the electron from the metal surface is called work function. ie. w = hυ₀ 4. The intensity of incident light is directly proportional to photoelectric current. 5. The kinetic energy of emitted electron is directly proportional to frequency of incident light. 6. A -ve potential is applied to anode plate just stop the photoelectric current is called stopping potential.
