The wave theory predicts that electrons will be ejected from a metal surface by any light with
(A) frequency above a threshold.
(B) frequency below a threshold.
(C) sufficient intensity.
(D) frequency near a resonance.
Questions
--- 
What this question is about
(A) frequency above a threshold. --- No.
That is what really happens.
The wave theory does not predict it.
Questions
--- What this question is about
(B) frequency below a threshold. --- No.
The frequency should not matter,
according to the wave theory.
Questions
--- What this question is about
(C) sufficient intensity. --- Yes.
Only the electric field should matter.
The prediction fails, however.
Questions
--- What this question is about
(D) frequency near a resonance. --- No.
The wave theory does not require that.
