Is photoelectric effect possible at all frequencies? Hence, we can say that photoelectric emission only occurs when the frequency of the incident radiation is greater than the threshold frequency or we can say that photoelectric emission does not occur at all frequencies. Why photoelectric effect is not possible at all frequencies? so as we decrease […]
