The photoelectrons emitted from a metal surface:

A light beam of interest 3.01xx10^(-3) W m ^(-2) is incident normally on the square -sapped metal surface of side 1 cm and with work function 2 eV . The intensity of light is equal distributed among the three constituents' wavelength , 400 nm, 550 nm and 650 nm. Each photon emits one electron without any loss in the energy. The number of electrons emitted per second from the metal surface is

When the energy of the incident radiation is increased by 20%, the kinetic energy of the photoelectrons emitted from a metal surface increased from 0.5 eV to 0.8 eV. The work function of the metal is:

Photoelectrons emitted from a metallic surface are

When the energy of the incident radiation is increased by 20 % , kinetic energy of the photoelectrons emitted from a metal surface increased from 0.5 eV to 0.8 eV . The work function of the metal is

Photoelectrons emitted from a metallic surface are those which are

Assertion: A photosensitive surface is illuminated by a monochromatic light of wavelength lambda and intensity I. The number of photoelectrons emitted per second is doubled when the intensity of light is doubled. However, the maximum speed of emitted electrons remains unchanged. Reason: The number of electrons emitted per second is directly proportional to the intensity of the incident light. The kinetic energy of the emitted photoelectrons is independent of the intensity of the light.

Light of wavelength 5000 Å and intensity of 3.96 xx 10^(-3) watt//cm^(2) is incident on the surface of photo metal . If 1% of the incident photons only emit photo electrons , then the number of electrons emitted per unit area per second from the surface will be

The kinetic energy of most energetic electrons emitted from a metallic surface is doubled when the wavelength lamda of the incident radiation is changed from 400 nm to 310 nm. The work function of the metal is
