In the photoelectric effect, electrons are never emitted from a metal if the frequency of the incoming light is below a certain threshold value. This is becauseA. Photons of lower-frequency light don’t have enough energy to eject an electron.B. The electric field of low-frequency light does not vibrate the electrons rapidly enough to eject them.C. The number of photons in low-frequency light is too small to eject electrons.D. Low-frequency light does not penetrate far enough into the metal to eject electrons.
How does Einstein’s explanation account for each of these characteristics of the photoelectric effect?a. The photoelectric current is zero for frequencies below some threshold.b. The photoelectric current increases with increasing light intensity.c. The photoelectric current is independent of ΔV for ΔV ≥ 1 V.d. The photoelectric current decreases slowly as ΔV becomes more negative.e. The stopping potential is independent of the light intensity.Which of these cannot be explained by classical physics? Explain.
When the photoelectric effect experiments were performed, one effect was inconsistent with classical physics. What was it?
O A. The kinetic energy of the ejected electrons increased as the wavelength of light decreased.
O B. The kinetic energy of the ejected electrons increased as the frequency of light increased.
O C. The fact that light could free electrons from the surface of a metal.
O D. The kinetic energy of the ejected electrons did not vary with light intensity.
