Question
Photons with energy 2.65×1019J (this corresponds to
400 THz frequency) illuminate two metal surfaces, A
and B. Electrons with kinetic energy, 0.65 ×1019 J, are
emitted from surface A. No electrons are emitted
from surface B. Which of the following statements is
FALSE?
The work function of metal surface A is
А
2.00x10-19 J.
The work function of metal surface B is
В
greater than 2.65×10-19 J.
To get emission of electrons from surface B
C
we need light with higher frequency.
To get emission of electrons from surface B
we need light with lower frequency.
