    When light of sufficiently high frequency is incident on a metallic surface, electrons are emitted from the metallic surface. This phenomenon is called photoelectric emission. Kinetic energy of the emitted photoelectrons depends on the wavelength of incident light and is independent of the intensity of light. Number of emitted photoelectrons depends on intensity. (hv-phi) is the maximum kinetic energy of emitted photoelectron (where phi is the work function of metallic surface). Reverse effect of photo emission produces X-ray. X-ray is not deflected by electric and magnetic fields. Wavelength of a continuous X-ray depends on potential difference across the tuve. Wavelength of charasteristic X-ray depends on the atomic number. Q. A monochromatic light is used in a photoelectric experiment on photoelectric effect. The stopping potential

    A point source of light is taken away from the experimental setup of photoelectric effect. For this situation, mark out the correct statement (s).

    In the experimental arrangement of photoelectric effect, the metal surface is first illuminated with violet light and then with ultraviolet light and the stopping potential is determined in each case. The stopping potential will
