Question: In a photoelectric experiment, if the stopping potential is increased, what happens to the energy of the emitted electrons?

Options:

Correct Answer: It remains the same

Solution:

The stopping potential does not affect the energy of the emitted electrons; it only affects the number of electrons reaching the detector.

In a photoelectric experiment, if the stopping potential is increased, what happens to the energy of the emitted electrons?

In a photoelectric experiment, if the stopping potential is increased, what happens to the energy of the emitted electrons?

Step 1: Understand what stopping potential means. It is the voltage needed to stop the emitted electrons from reaching the detector.
Step 2: Know that the energy of emitted electrons comes from the light that hits the material, not from the stopping potential.
Step 3: Realize that increasing the stopping potential means you are applying a stronger voltage to stop more electrons.
Step 4: Conclude that while more electrons can be stopped, the energy of the electrons that are emitted remains the same.

Photoelectric Effect – The phenomenon where electrons are emitted from a material when it is exposed to light of sufficient frequency.
Stopping Potential – The minimum potential difference needed to stop the most energetic emitted electrons from reaching the detector.
Kinetic Energy of Electrons – The energy of the emitted electrons is determined by the frequency of the incident light and the work function of the material, not the stopping potential.
