Photoelectric Effect Flashcards
1
Q
Work Function
A
Energy required to remove an electron from a surface
2
Q
Threshold Frequency
A
Minimum frequency needed to remove an electron
3
Q
Photoelectrons will be released if the incident radiation has a frequency above the…
A
Threshold Frequency
4
Q
How many photoelectrons does 1 photon release?
A
1
5
Q
If the radiation is above the threshold frequency, making more intense will…
A
Increase the number of photoelectrons that are released
6
Q
What does the kinetic energy depend on?
A
Frequency only
7
Q
Why do we say KE max?
A
As we assume all incident energy is converted into kinetic energy
