Question: In the photoelectric effect, what is the relationship between the energy of the incident photon and the kinetic energy of the emitted electron?

Options:

K.E. = E_photon - Work function
K.E. = Work function - E_photon
K.E. = E_photon + Work function
K.E. = E_photon * Work function

Correct Answer: K.E. = E_photon - Work function

Solution:

The kinetic energy of the emitted electron is equal to the energy of the incident photon minus the work function of the metal.

In the photoelectric effect, what is the relationship between the energy of the incident photon and the kinetic energy of the emitted electron?

Step 1: Understand that a photon is a particle of light that carries energy.
Step 2: Know that when a photon hits a metal surface, it can transfer its energy to an electron in the metal.
Step 3: Recognize that each metal has a specific amount of energy required to release an electron, called the work function.
Step 4: The energy of the incident photon is compared to the work function of the metal.
Step 5: If the energy of the photon is greater than the work function, the excess energy becomes the kinetic energy of the emitted electron.
Step 6: The relationship can be expressed as: Kinetic Energy of emitted electron = Energy of incident photon - Work function of the metal.

Photoelectric Effect – The phenomenon where electrons are emitted from a material when it absorbs light (photons).
Photon Energy – The energy of a photon is directly proportional to its frequency and inversely proportional to its wavelength.
Work Function – The minimum energy required to remove an electron from the surface of a metal.
Kinetic Energy of Emitted Electrons – The energy of the emitted electrons is the difference between the photon energy and the work function.
