In a particular experiment to study the photoelectric effect, the frequency of the incident light and the temperature of the metal are held constant. assuming that the light incident on the metal surface causes electrons to be ejected from the metal, what happens if the intensity of the incident light is increased? check all that apply. the choices are: the work function of the metal decreases. the number of electrons emitted from the metal per second increases. the maximum speed of the emitted electrons increases. the stopping potential increases. part b: in another experiment, the intensity of the incident light and the temperature of the metal are held constant. assuming that the initial light incident on the metal surface causes electrons to be ejected from the metal, what happens if the frequency of the incident light is increased?

Which statement below concerning the photoelectric effect is true? view available hint(s) which statement below concerning the photoelectric effect is true? there is a threshold frequency for each metal, and only light of a frequency higher than this threshold causes electrons to be emitted from the metal surface. light with a frequency below the threshold frequency can still cause electrons to be emitted from the metal surface, but there will be a lag time while sufficient energy to dislodge the electrons builds up. there is a threshold wavelength for each metal, and only light of a longer wavelength than this threshold causes electrons to be emitted from the metal surface. increasing the intensity (amplitude) of the light shined on a metal surface is sufficient to cause the emission of electrons from a metal surface.

You will become familiar with two effects/experiments important u l in this exercise development of quantum theory, the photoelectric effect and electron scattering from a metal crystal. these explanation of these experiments indicate the particle property of light and wave property of mater respectively. both of these effects have important modern applications of these properties have had large scientific and technological significance. electron microscopy is based on the same concepts as are needed to understand electron diffraction. the photoelectric effect has lead to photodiode and photo-sensing technologies and a revolution in the understanding of atoms and molecules through spectroscopic techniques 1) photoelectric effect. (14 points) when light is shown onto the negative plate of a capacitor the following observations are made. explain briefly how each observation is consistent with the idea that the incident light consists of particles with energy, hu, that undergo collision with electrons in the metal. a. no electrons are ejected regardless of the intensity of radiation, unless the frequency of the incident light exceeds a certain threshold such that the energy of the light quanta are at least as much as the work function of the metal, d, (2 points provided that the frequency of the incident radiation is high enough to eject electrons, the kinetic energy of the ejected electrons increases linearly with the frequency of the incident radiation but is independent of the intensity of the radiation. (2 points even at low intensities, electrons are ejected immediately if the frequency is above the threshold.
