Question: In a photoelectric experiment, if the stopping potential is increased, what does it indicate about the emitted electrons?

Options:

Correct Answer: They have higher kinetic energy

Solution:

Increasing the stopping potential indicates that the emitted electrons have higher kinetic energy, as more energy is required to stop them.

In a photoelectric experiment, if the stopping potential is increased, what does it indicate about the emitted electrons?

In a photoelectric experiment, if the stopping potential is increased, what does it indicate about the emitted electrons?

Step 1: Understand what stopping potential means. It is the voltage needed to stop emitted electrons from reaching the detector.
Step 2: Know that emitted electrons come from a material when light hits it in a photoelectric experiment.
Step 3: Realize that when light hits the material, it gives energy to the electrons, allowing them to escape.
Step 4: If the stopping potential is increased, it means that the electrons are moving faster and have more energy.
Step 5: Conclude that a higher stopping potential indicates that the emitted electrons have higher kinetic energy.

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, indicating their kinetic energy.
Kinetic Energy of Electrons – The energy that the emitted electrons possess, which can be inferred from the stopping potential.
