If Light at 193 Nm from an Argon-Fluoride Laser Is $\times$

Short Answer

If light at 193 nm from an argon-fluoride laser is incident on a gold metal surface,electrons with kinetic energy of 1.80 $\times$ 10^-19 J are produced.What is the work function of gold in kJ/mol? What is the minimum wavelength of light in nm required to produce photoelectrons from gold (zero kinetic energy)?
