Light of a particular wavelength does not eject electrons from the surface of a given metal. Should the wavelength of the light be increased or decreased in order to cause electrons to be ejected?
Â
Part II: Choose the best explanation from among the following:
Â
The photons have too little energy to eject electrons. To increase their energy, their wavelength should be increased.Â
Â
The energy of a photon is proportional to its frequency; that is, inversely proportional to its wavelength. To increase the energy of the photons so they can eject electrons, one must decrease their wavelength.
