SUMMARY
The maximum kinetic energy of a particle can be calculated using the formula KE = hc/λ – Φ, where Φ represents the work function. In this discussion, the work function is given as 3.6 eV and the wavelength of the incident photon is 250 nm. By substituting these values into the equation, one can determine the maximum kinetic energy of the particle. The conservation of energy principle is applied, where the energy of the photon is partially used to overcome the work function, with the remainder contributing to the kinetic energy.
