(iii) Electromagnetic radiation of wavelength 580 nm is incident on an uncharged surface of a metal X, in vacuo. Electrons are ejected from the metal surface and are attracted to a nearby positively charged electrode causing a photoelectric current to flow. As the potential on the nearby electrode is decreased, the photoelectric current decreases and becomes zero when the electrode potential is -0.3 V. Calculate the maximum velocity of the photoelectrons ejected from the metal surface.

Question
**Photoelectric Effect Problem** **Problem Statement:** Electromagnetic radiation of wavelength 580 nm is incident on an uncharged surface of a metal X, in vacuo. Electrons are ejected from the metal surface and are attracted to a nearby positively charged electrode causing a photoelectric current to flow. As the potential on the nearby electrode is decreased, the photoelectric current decreases and becomes zero when the electrode potential is -0.3 V. Calculate the maximum velocity of the photoelectrons ejected from the metal surface. **Explanation:** This problem involves the photoelectric effect, where photons with a wavelength of 580 nm strike a metal, causing electrons to be ejected. The key point is understanding that as the electrode potential decreases to -0.3 V, the photoelectric current ceases, indicating the potential energy required to stop the ejected electrons. **Graph/Diagram Explanation:** There are no graphs or diagrams provided in the text.
