Lesson 22.1: A Particle Model of Waves – Worksheet Summary (Key Points Only)
· Calculate photon energy from frequency or wavelength, and convert between joules and electron volts.
· Find photon wavelength from frequency.
· Calculate the maximum kinetic energy of emitted electrons using photon energy and work function.
· Determine stopping potential from maximum kinetic energy.
· Calculate photon momentum from wavelength.
· Decide if electron emission occurs by comparing photon energy to work function (or wavelength to threshold wavelength).
· Convert electron speed to kinetic energy (joules and eV).
