Which of the following is correct regarding photo-electric effect? (i) The photo-electric effect takes place if lambda le lambda_(0) or upsilon ge upsilon_(0) . maximum K.E. of photo-electron K_(max) =hv=(hc)/(lambda) Einstein photo-electric effect equation hv=hv_(0) + K_(max) (ii) The maximum K.E. of electron or stopping potential V_(s)(K_(max) =eV_(s)) for a given metal depends only on frequency or wavelength of incident light and not on its intensity (iii) The saturation current (i =ne, n: number of photo-electrons ejected per unit time) depends on intensity and not frequency (iv) Normally it is assumed that one photon eject one electron. Practically several incident photons eject one electron. If quantum efficiency is given {"Quantum efficiency" =("Number of electrons ejected")/("Number of photons incident")} Number of electrons ejected must be calculated must be calculated and then calculate saturation current
