Chapter 38, Problem 31P(choose chapter or problem)
Problem 31P
When a certain photoelectric surface is illuminated with light of different wavelengths, the following stopping potentials are observed:
Wavelength (nm) |
Stopping potential (V) |
366 |
1.48 |
405 |
1.15 |
436 |
0.93 |
492 |
0.62 |
546 |
0.36 |
