The photoelectric effect provided evidence that supported the early suggestion by Max Planck that electromagnetic waves exist as discrete packets of energy. a. Describe the energy transformations that occur during the photoelectric effect. b. If the incident light was not causing the emission of any electrons from the target metal, how could the light be changed to start causing emission of electrons? Explain your answer. c. Rather than changing the light source, explain why changing the target metal from part (c) may allow for the detection of emitted electrons.
QUESTION You have a large, healthy philodendron that you carelessly leave in total darkness while you are on vacation. You are surprised to find that it is still alive when you return. What has the plant been using for an energy source while in the dark? A. When light energy is not available, plants can derive energy from inorganic molecules. B. Even though the plant received no visible light, it was able to use the short-wave part of the electromagnetic spectrum (gamma rays and X-rays) to carry out photosynthesis. C. While it did have access to light, the plant stored energy in the form of sugars or starch, and it was able to derive energy from the stored molecules during your vacation. D. Even though it can't carry out the light reactions, the plant can still produce sugars because the Calvin cycle doesn't require light. E. None of the above.
PHOTOELECTRIC EFFECT I. Which of the following observations from the photoelectric effect is NOT VIOLATION of classical physics?? A. Light can eject electrons from semi conductive material B. Light intensity does not influence the kinetic energy of ejected electrons C. Electrons are ejected immediately after impact from light II. According to wave theory, what is the nessesary to eject electrons from surface?? A. A frequency that is higher than that of the electrons at the surface B. A very small number of photons C. Enough energy to overcome the binding energy of the electrons III. The minimum frequency of radiation at which electrons will be ejected is called the threshold frequently go. TRUE OR FALSE??
