In the diagram shown above, which label corresponds to the threshold frequency for the photoelectric effect of a metal with a work function of 2.14 eV?
A
Label A: 5.16 x 10^14 Hz
B
Label B: 3.00 x 10^14 Hz
C
Label C: 6.63 x 10^-34 J s
D
Label D: 4.00 x 10^15 Hz
Correct Answer
Option A
Detailed Explanation
The threshold frequency is calculated using the work function. For a work function of 2.14 eV, the threshold frequency is 5.16 x 10^14 Hz as derived from the equation .
