1) Light of wavelength 310nm is shined on a metal with work function = 1 eV. What will be the maximum kinetic energy of the emitted electrons?
2) Light is shined on a metal with work function 2.0 eV, and electrons are emitted creating a photocurrent. When a decelerating voltage of magnitude 1.0 V is applied, the current goes to zero (i.e. the magnitude of the stopping voltage is 1V). What is the wavelength (in nm) of the incoming light?
3) According to the wave model of light, which would have a larger stopping potential (or would their stopping potentials be the same): bright green light of a single wavelength, or dim green light of the same wavelength? Explain your answer.
4) According to Einstein’s model of light, which would have a larger stopping potential (or would their stopping potentials be the same): bright green light of a single wavelength, or dim green light of the same wavelength? Explain your answer
5) Blue light has a higher frequency than green light. According to Einstein’s model of light, which would have a larger stopping potential: blue light or green light (or do you need more information to answer this question)? Explain your answer.
6)In this lab you will measure stopping voltage vs. wavelength for several wavelengths of light. If the Einstein model is correct, use the equations in the introduction to explain how you can plot your data in a way so as to acheive a straight line. What will be the slope and intercept of this line?
