If the wavelength of incident light changes from 400 nm to 300 nm, the stopping potential for photoelectrons emitted from a surface becomes approximately

In a photoelectric experiment, the wavelenght of the light incident on a menatl is changed from 300 nm to 400nm. The decreases in the stopping potential is close to : ((hc)/(e) = 1240 nm -V)

Light of wavelength 3 xx 10^(-7) m is incident on a photosensitive surface . The stopping potential for emitted photoelectrons is 2.5 V . If the wavelength of incident light is reduced to 1.5 xx 10^(-7) m , the stopping potential for emitted photoelectrons is

Stopping potential of emitted photo electron is V when monochromatic light of wavelength 'lamda' incident on a metal surface. If wavelength of light incident becomes 'lambda/3' stopping potential of photoelectrons becomes V/4 then the threshold wavelength of metal is k'lambda' then k will be
