Which of the following statements are true for the photo-electric effect? (select true or false) True False The maximum energy of the ejected electrons is proportional to the intensity of the incoming photons. True False The maximum energy of the ejected electrons varies linearly with the frequency of the incoming photons. True False The frequency of the photons must be larger than a certain minimum value in order to eject electrons from the metal. True False The maximum energy of the ejected electrons is...
