PhysicsHardsingle choice

The frequency of incident light falling on a photosensitive metal plate is doubled, the kinetic energy of the emitted photoelectrons is

Answer:

Solution:

Since, $λ_{r} > λ_{y} > λ_{g}$ the wevelength of red light is greater than threshold wavelength and hence no electrons are emitted.
