Q: In the photoelectric effect, the kinetic energy of the emitted electrons depends on which of the following?
Solution: The kinetic energy of the emitted electrons in the photoelectric effect depends on the frequency of the incident light, as per Einstein's photoelectric equation.
Steps: 8
Step 1: Understand the photoelectric effect. This is when light hits a material and causes it to emit electrons.
Step 2: Know that light can be thought of as made up of tiny packets of energy called photons.
Step 3: Realize that each photon has a specific frequency (or color) and energy associated with it.
Step 4: Learn that the energy of a photon is directly related to its frequency. Higher frequency means more energy.
Step 5: Understand that when a photon hits an electron, it can transfer its energy to the electron.
Step 6: If the energy from the photon is greater than a certain threshold (the work function of the material), the electron is emitted.
Step 7: The kinetic energy of the emitted electron is equal to the energy of the photon minus the work function of the material.
Step 8: Therefore, the kinetic energy of the emitted electrons depends on the frequency of the incident light.
