Take h to have an exact value of 6.63x10-34J-s for significant figure purposes, and use hc=1.24x103eV-nm (three significant figures). When a certain photoelectric material is illuminated with red light (A=690) and then blue light (A=410), it is found that the maximum kinetic energy of the photoelectrons resulting from the blue light is twice that from red light. Part A) What is the work function of the material? po= ? eV
