QUESTION 5 Two electron sources are designed using lasers with different wavelengths

QUESTION 5 Two electron sources are designed using lasers with different wavelengths directed at different metal surfaces. The first source uses a 181 nm laser and the metal has a work function of 4.4 eV. The second source uses 213 nm light, but an unknown metal surface. If both sources produce electrons with the same maximum kinetic energy, what is the work function of the second metal. Provide your answer in eV, correct to two decimal places. 2.57
