Light is shining on a metallic surface causing electron to be ejected. Increasing the frequency of (a) causes ejected electrons to have more kinetic energy (b) causes ejected electrons to have less velocity (c) causes even more electrons to be ejected (d) causes no change to the ejected electrons or to the number of ejected electrons (e) none of the above The greater the work function for a metal, a) the greater the speed ofthe ejected electron b) the smaller the speed of the ejected electron ( l (c) the more electrons are ejected (d) the lower the threshold frequency (e) none of the above In the photoelectric effect, increasing the frequency of the light incident on a metal surface (a) decreases the threshold frequency for the emission of photoelectrons (b) decreases the number of photoelectrons emitted (c) increases the threshold frequency for the emission of photoelectrons (d) increases the kinetic energy of the most energetic photoelectrons (e) does not affect the kinetic energy ofthe photoelectrons
