Explanation:
Stopping potential in Photoelectric Effect:
- When light of sufficient frequency falls on a metal surface, photoelectrons are emitted.
- The stopping potential is the minimum potential required to stop these emitted photoelectrons.
Effect of Ultraviolet and Infrared Radiations:
- Ultraviolet radiation has a higher frequency than infrared radiation.
- Higher frequency light means higher energy photons.
- Therefore, ultraviolet light can provide more energy to the electrons and eject them with higher kinetic energy compared to infrared light.
Stopping Potential in Ultraviolet vs Infrared:
- When subjected to ultraviolet radiation, the stopping potential for photoelectrons will be higher due to the higher energy of the photons.
- This is because the photoelectrons will have more kinetic energy and require a higher potential to stop them.
- Hence, the stopping potential will be more when ultraviolet light is used compared to infrared light.
Therefore, the correct answer is option B) More when ultraviolet is used.
