Photocurrent and Light Intensity
The correct statement is option 'C' - The photocurrent increases with increasing intensity of light.
Explanation:
When light falls on the surface of a photocell, electrons in the material absorb energy from the photons and are excited to higher energy levels. If the energy of the photons is greater than the work function of the material, the electrons can be emitted from the surface of the material, resulting in a flow of current.
The photocurrent generated by a photocell is directly proportional to the intensity of the incident light. This is because the greater the number of photons incident on the photocell, the greater the number of electrons that are excited and emitted from the surface, resulting in a greater photocurrent.
Mathematically, the relationship between the photocurrent and the incident light intensity can be expressed as:
I ∝ I0
where I is the photocurrent, I0 is the incident light intensity, and the proportionality constant depends on the properties of the photocell.
Therefore, option 'C' is the correct statement.
