Calculation of the Work Function of Nickel

To calculate the work function of nickel, we can use the equation that relates the maximum kinetic energy of the photoelectrons to the energy of the incident photons and the work function. The equation is as follows:

Maximum Kinetic Energy of Photoelectrons = Energy of Incident Photons - Work Function

Given that the maximum kinetic energy of the photoelectrons is 15.48 * 10^-19 J and the energy of the incident photons is 23.22 * 10^-19 J, we can substitute these values into the equation and solve for the work function.

15.48 * 10^-19 J = 23.22 * 10^-19 J - Work Function

To find the value of the work function, we subtract the energy of the incident photons from the maximum kinetic energy of the photoelectrons:

Work Function = Energy of Incident Photons - Maximum Kinetic Energy of Photoelectrons

Work Function = 23.22 * 10^-19 J - 15.48 * 10^-19 J

Calculating the difference, we find:

Work Function = 7.74 * 10^-19 J

Therefore, the work function of nickel is approximately 7.74 * 10^-19 J.

Please note that the above calculation is based on the provided values and assumes that the energy of the incident photons is equal to the maximum kinetic energy of the photoelectrons.
