Question

monochromatic light is incident on the surface of a metal with work function

2.50 eV. If a 1 V stopping potential is required to make the photo current zero,

what is the wavelength of light?​

Answer 1

Explanation:

• Monochromatic light of wavelength 198 nm is incident on the surface of a metal, whose work function is 2-5 eV. ... When photons strike the metal plate photoelectrons are emitted from it. This effect is called photoelectric effect. Definition: Wavelength can be defined as the distance between two successive crests or troughs of a wave. ... The wavelength of UV radiation is shorter than violet light. Similarly, the wavelength of infra red radiation is longer than the wavelength of red light. Wavelength is inversely proportional to frequency.
