The Threshold Frequency for the Photoelectric Effect of a Particular

Multiple Choice

The threshold frequency for the photoelectric effect of a particular metal is 3.0×10¹⁴ sec ^{- 1}. When this metal is illuminated by light with a frequency of 2.0×10¹⁴ sec ^{- 1}, which of the following is true?

A) The kinetic energy of the emitted electrons is greater than those emitted by light at the threshold frequency.
B) The number of electrons emitted is greater than that emitted by light at the threshold frequency.
C) The light energy absorbed by the metal decreases the distance between atoms.
D) No electrons will be emitted due to the photoelectric effect.
E) None of these are true.
