The photocurrent is `I_(P)` when a certain number of photons is incident on a photosensitive plate. If the number of photons is doubled, the photocurrent will be

Light of frequency 1.5 times the threshold frequency is incident on photo-sensitive material. If the frequency is halved and intensity is doubled, the photocurrent becomes

10 photons each of energy 1.5 eV are made incident on a photosensitive plate whose work function is 3 eV. The number of electrons emitted from the plate will be

In one joule of energy, the number of photons with have number equal to x is

In one joule of energy, the number of photons with wave number equal to x 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

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