- PLEASE be clear in your answer since the last time I posted was incorrect and only answer part a, thanks.arrow_forwardNeed help with prob 2. Please show your work and box your answer thank youarrow_forwardONLY ANSWER 3 AND USE OTHER QUESTIONS FOR CONTEXT Suppose we have two sources of light, a deep red one with wavelength 700 nm, and a violet one with wavelength 400 nm. Both produce the same optical power, delivering 1 milliwatt (10−310−3 watts) of energy per second per square centimeter to a metal target with an area of 1cm2 located 1 meter from the sources. 1. Which color would deliver more photons each second? All the photoelectrons that are produced from the light are presumed to be collected by another electrode and we determine the current in amperes using a circuit and an "ammeter", that is, some device that can give a precise quantitative measure of the current. Such a device might use the magnetic field generated by the current, or the voltage produced when the current flows across a resistance. 2. If the work function of the surface is 2 eV, will we see a current with both colors, one color, or neither one? If so, how much (in amperes), or if not, explain. 3. If we now…arrow_forward
