Question 1.
What is photoelectric current?
Show hintHide hint
Think about how light interacts with electrons.
Question 2.
Define saturation current.
Show hintHide hint
What happens when every electron is captured?
3Question 3.
What happens to photoelectric current when positive potential is increased?
- It decreases
- It increases until saturation
- It stays the same
Show hintHide hint
What marks the endpoint of current increase?
4Question 4.
The stopping potential is the value at which:
- True
- False
Show hintHide hint
What does a stopping potential indicate about electron movement?
Question 5.
A photosensitive material emits electrons forming a current. Explain the experimental setup that would determine the effects of varying intensity and frequency on the photoelectric current created. What considerations must be made when varying the collector potential?
Show hintHide hint
Think about how varying both the light and the setup's characteristics will influence the observed results.
Question 6.
Define and derive the relationships between the stopping potential and the maximum kinetic energy of photoelectrons in the context of the photoelectric effect.
Show hintHide hint
Link the stopping potential to electron interactions with photons.
