The work function of a metal is . Light of frequency falls on this metal. The photoelectric effect will take place only if
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
According to Einstein's photoelectric equation, hν-W=Kmax, where h=Plank's constant, ν=frequency of radiation, W=work function and Kmax=maximum kinetic energy of photoelectron. ∵Kmax≥0, as kinetic energy can't be negative.…
