Question 6

In an experiment demonstrating the photoelectric effect, it is observed that electrons are only ejected from a metal surface if the incident light's frequency exceeds a specific threshold, irrespective of the light's intensity. Furthermore, for frequencies above this threshold, increasing the light's intensity increases the *number* of ejected electrons, but not their *maximum kinetic energy*. This set of observations provides strong evidence for which of the following?

Accepted Answer

C. The quantum nature of light, where energy is transferred in discrete packets called photons. — Option C accurately reflects that the quantum nature of light, specifically the photon concept (E=hν), is required to explain the observed phenomena of the photoelectric effect. The existence of a threshold frequency implies that energy is transferred in discrete packets (photons), each needing sufficient energy to overcome the metal's work function. Classical wave theory (Option B) fails to explain the threshold frequency and predicts that electron kinetic energy should increase with light intensity, contradicting observations. Options A and D are unrelated or do not provide the fundamental e
