A light wave with wavelength 590nm shines upon a metal and causes it to emit an electron with a speed of 5x10^5 m/s. What is the work function of the metal?

The first step for this question is to find out how much energy is absorbed by the electron above its work function. This is found with the kinetic energy equation: K.E.=1/2mv^2 The mass of an electron is 9....
