Here is the answer for the question - 2. Which statement below concerning the photoelectric effect is true?. You'll find the correct answer below

2. Which statement below concerning the photoelectric effect is true? Hints A. Light with a frequency below the threshold frequency can still cause electrons to be emitted from the metal surface, but there will be a lag time while sufficient energy to dislodge the electrons builds up. B. Increasing the intensity (amplitude) of the light shined on a metal surface is sufficient to cause the emission of electrons from a metal surface. C. There is a threshold wavelength for each metal, and only light of a longer wavelength than this threshold causes electrons to be emitted from the metal surface. D. There is a threshold frequency for each metal, and only light of a frequency higher than this threshold causes electrons to be emitted from the metal surface.

The Correct Answer is

There is a threshold frequency for each metal, and only light of a frequency higher than this threshold causes electrons to be emitted from the metal surface.

Reason Explained

There is a threshold frequency for each metal, and only light of a frequency higher than this threshold causes electrons to be emitted from the metal surface. is correct for 2. Which statement below concerning the photoelectric effect is true?
