Monochromatic light with a frequency well above the cutoff frequency is incident on the emitter in a photoelectric effect apparatus. The frequency of the light is then doubled while the intensity is kept constant. How does this affect the photoelectric current?
Options:
Answer:
B
Solution:
At fixed intensity, doubling frequency halves photon rate With unchanged quantum yield and collection, photocurrent decreases
