Question

According to Einstein's photoelectric equation, the graph between the kinetic energy of photoelectron ejected and the frequency o the incident radiation is

• A.
• B.
• C.
• D.

Answer 1

Answer: (C)

According to Einstein's photoelectric equation, the graph between the kinetic energy of photoelectron ejected and the frequency o the incident radiation is

As when $v=v_0$ , the kinetic energy of photoelectrons is zero, further the K.E. of photoelectrons increases with increase in the frequency of the radiation.
