If this light falls on a metal surface having a work function of 2.0eV, what will be the maximum kinetic energy of the photoelectrons ?

The magnetic field at a point associated with a light wave is B = 2 × 10^−6 Tesla sin[(3.0 × 10^15 s^−1 )t] sin[(6.0 ×10^15 s^−1 )t]. If this light falls on a metal surface having a work function of 2.0eV, what will be the maximum kinetic energy of the photoelectrons ?

Ultraviolet beam of wavelength 280 nm is incident on lithium surface of work function 2.5 eV. The maximum velocity of electron emitted from metal surface is
