307395 Light of wavelength \(\mathrm{\lambda}\) shines on a metal surface with intensity \(\mathrm{\mathrm{x}}\) and the metal emits \(\mathrm{\mathrm{Y}}\) electrons per second of average energy, Z. What will happen to \(\mathrm{\mathrm{Y}}\) and \(\mathrm{\mathrm{Z}}\) if \(\mathrm{\mathrm{x}}\) is doubled?

307396 The minimum energy required to overcome the attractive forces of electron and surface of Ag metal is \({\rm{5}}{\rm{.52 \times 1}}{{\rm{0}}^{{\rm{ - 19}}}}{\rm{J}}\). What will be the maximum K.E. of electron ejected out from Ag which is being exposed to U. V. light of \({\rm{\lambda = 360}}\mathop {\rm{A}}\limits^ \circ \)?

307397 Light of wavelength \(\lambda\) falls on metal having work function hc \(/ \lambda_{0}\). Photoelectric effect will take place only if

307398 Read Assertion and Reason carefully and mark correct option.
Assertion :
In the photoelectric effect, the electrons are ejected from the metal surface as soon as the beam of light of frequency greater than threshold frequency strikes the surface.
Reason :
When the photon of any energy strikes an electron in the atom, transfer of energy from the photon to the electron takes place.
