Calculating Ionization Energy

Postby ValerieChavarin 4F » Fri Nov 01, 2019 1:44 pm

In my discussion we did a problem that was essentially the following:
Calculate the ionization energy of RB given that a radiation with the wavelength of 58.4nm produces electrons with a velocity of 240km/s, when it hits RB.

Why do we solve for the work function?

Work function is also known as threshold energy which is the amount of energy needed to remove an electron from a metal. So, it is similar to ionization energy but ionization energy is with elements in the gas ohase while this equation with work function is with metals
