The frequency of incident light falling on a photosensitive metal plate is doubled, the K.E of the emitted photo-electrons is

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

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

If the frequency of incident light falling on a photosensitive metal is doubled, the kinetic energy of the emitted photoelectron is

If the wavelength of incident light falling an a photosensitive material decreases, then

When the frequency fo light incident an a metallic plate is doubled , the 1KE of the emitted photoelectrons will be :
