Energy absorbed by electron is used in
A)escaping the metal
B)increasing kinetic energy
C)both A and B
D)increasing frequency

Question

Quizplus · Accepted Answer

Energy absorbed by an electron is used both for escaping the metal, which is the work function, and for increasing its kinetic energy once it has escaped. The frequency of an electron does not increase with energy absorption; instead, it's the frequency of electromagnetic waves that can be associated with such changes.
