5. A physicist is asked to analyze two mystery metals. Each metal is struck by light with three different wavelengths: 300 nm, 400 nm, and 500 nm. In each case, the physicist adjusts the voltage gradient to determine the energies of the emitted electrons. The results are shown in the chart below. What are the values of X and Y? Wavelength Mystery Metal A Mystery Metal B 300 nm 2.9 eV 1.8 eV 400 nm X 0.8 eV 500 nm 1.3 eV Y OAX OBX O C. X O D. X = 1.9 eV, Y = 0.2 eV 2.1 eV, Y cannot be determined 2.1 eV, Y = 0.2 eV - 1.9 eV, Y cannot be determined 5. A physicist is asked to analyze two mystery metals.
