For photoelectric emission from certain metal the cutoff fequency is v.If radiation of frequency 2 v impinges on the metal plate,the maximum possible velocity of the emitted electron will be (m is the electron's mass),

For photoelectric emission from certain metal the cut - off frequency is v . If radiation of frequency 2 v impinges on the metal plate , the maximum possible velocity of the emitted electron will be ( m is the electron mass).

The photoelectric threshold frequency of a metal is v_0. When ligth of frequency 3v_0 is incident on the metal, the maximum kinetic energy of emitted photoelectrons will be

The photoelectric threshold frequency of a metal is v. When light of frequency 4v is incident on the metal . The maximum kinetic energy of the emitted photoelectrons is

The metal that shows photoelectric emission at lowest frequency radiation is

Light of frequency 4 v_(0) is incident on the metal of the threshold frequency v_(0) . The maximum kinetic energy of the emitted photoelectrons is

The maximum velocity of the photoelectrons emitted from the surface is v when light of frequency n falls on a metal surface. If the incident frequency is increased to 3n, the maximum velocity of the ejected photoelectrons will be
