if the frequency increases and number of photos ejected remain same. the rate of ejection should increase . because frequency is in inverse relation with time. but here it is not so. can u kindly explain me this

    The kinetic energy of photoelectrons increases with light frequency. Electric current remains constant as light frequency increases. Electric current increases with light amplitude...

    the current is independent of the frequency of illuminated light but it depends on the intensity of light used in the process. While more intensity of light results in more number ...

    got madhumathy....here if we constant light amplitude then then the photon absorbed by the metal is also constant because intensity is kept constant...so however if we increase lig...

    see what ever be the intesity of incident light may be...but if the frequency of light doesn't exceed or overcome threshold frequency then no ejections of electrons is possible

    sir., but here it is written that frequency increases.
  • Dinesh khalmaniya
    yes, it's correct so what's your doubt??

    sir can you clearly differentiate between intensity and frequency.i keep on mixing up them.
