A metal having a threshold frequency of v_0//2 is illuminated by the incident radiation of frequency 2v_0 . If the energy of the incident photon is increased by 40 percent , then what will be the percentage change in the kinetic energy of the photoelectrons emitted from the surface of the metal ? Note that increase in energy of photon is done by suitably changing frequency of radiation.

For a certain metal the threshold frequency is v_(0) . If light of frequency 2v_(0) is incident on it the electron come out with a maximum velocity of 4xx10^(6) m/s. If light of frequency of 5v_(0) is incident on it the maximum velocity of the photo electron will be
