Question
Which equation correctly represents Einstein's Photoelectric Equation, relating the energy of a photon (hf), the work function (W), and the kinetic energy (KE) of the ejected electron?
Correct Answer
Option D is the correct answer.
Detailed Explanation
Page 3 clearly states the equation: 'hf = W + KE'. This equation represents the conservation of energy, where the photon's energy is used to overcome the work function and provide kinetic energy to the electron.
Hint
Think about how the photon's energy is 'spent' once it hits the metal.
