2.10 ev is the work function of Calcium. The metal is exposed to radiation with a wavelength equal to 100 nanometers. The following guiding questions are the procedure you would follow to find the kinetic energy of the electron released from the metal. If one ev is equal to 1.60218E-19 Joules.

1. What is needed to remove the electron from the metal?

2. What is the energy of the photon with which the metal is irradiated in Joules?

3. Calculate the kinetic energy value in Joules for the electron in this exercise, following the class formula?

4. What can you conclude based on the calculated kinetic energy value?
