Which is true?
The photoelectric effect occurs only for frequencies below the cutoff frequency, regardless of the intensity.
b The photoelectric effect occurs only for frequencies above the cutoff frequency, regardless of the intensity.
c The photoelectric effect occurs only for frequencies below the cutoff frequency and only for intensities above a cutoff intensity.
d The photoelectric effect occurs only for frequencies above the cutoff frequency and only for intensities above a cutoff intensity.
aThe photoelectric effect occurs only for frequencies below the cutoff frequency, regardless of the intensity.
Explanation / Answer
True statement is statement number 2.
The photoelectric effect occurs only for frequencies above the cutoff frequency, regardless of the intensity.
because even if it's not very intense and light is above cutoff frequency the electrons will be emitted everytime.
