In a photoelectric experiment, increasing the intensity of incident light :
Multiple Choice Options
- A increases the number of photons incident and also increases the K.E. of the ejected electrons
- B increases the frequency of photons incident and increases the K.E. of the ejected electrons
- C increases the frequency of photons incident and the K.E. of the ejected electrons remains unchanged
- D increases the number of photons incident and the K.E. of the ejected electrons remains unchanged
Step-by-Step Verified Solution
Increasing intensity means number of incident photons are increased.
Kinetic energy of ejected electrons depend on the frequency of incident photons, not the intensity.
Kinetic energy of ejected electrons depend on the frequency of incident photons, not the intensity.
