A photoelectric experiment was performed by separately shining a laser at 450nm (blue light) and a laser at 560nm (yellow light) on a clean metal surface and measuring the number and kinetic energy of the ejected electrons. Which light would eject electrons with greater kinetic energy? Which light would generate more electrons? Assume that the same amount of energy is delivered to the metal surface by each laser and that the frequencies of the laser lights exceed the threshold frequency.
