Dual Nature of Radiation and Matter

Question:
If the intensity of the incident radiation is extremely dim, but the frequency of the radiation is 1.5 times the threshold frequency of the metal, what can we predict about the photoemission in this case?
Options:
The emission will occur if the intensity is increased
The emission will not take place
The emission will occur anyway
cannot predict
Correct Answer:
The emission will occur anyway
Explanation:
As the frequency is greater than that of the threshold, the emission will occur.
