Which of the following statements is TRUE of photoelectric effect?
it cannot occur in liquids
the energy of the emitted electrons is independent of the work function of the surface
the energy of the emitted electron depends on the wavelength of the incident light
the greater the intensity of the incuident light, the greater the incident of the emitted electron
Correct answer is C
The photoelectric effect is the emission of electrons when electromagnetic radiation, such as light, hits a material.
The frequency of the incident light on the substance determines the kinetic energy of the emitted electrons.
The number of electrons emitted and the intensity of light incident are proportional to each other.
