The threshold wavelength for a surface having a threshold frequency of `0.6xx10^(15) Hz` is (given `c=3xx10^(8)m//s`)

The kinetic energy of the electron emitted when light of frequency 3.5xx10^(15)Hz is made to strike on a metal surface havng threshold frequency 1.5xx10^(15)Hz is (h=6.6xx10^(-34)Js)

The kinetic energy of the electron emitted when light of frequency 3.5 xx 10^15 H z falls on a metal surface having threshold frequency 1.5 xx 10^15 H z is (h = 6.6 xx 10^-34 Js) .

A photon having 8 eV energy is incident on metal suraface with threshold frequency of 1.6xx10^(15) Hz .Maximum kinetic energy of photoelectron emitted will be……. h=6.6xx10^(-34)JS,c=3xx10^(8)m//s eV=1.6xx10^(-19)JS

If the threshold frequency be 2 xx 10^14 Hz , the work function is
