If a photocell is illuminated with a radiation of , the stopping potential is found to be ; then the work function of the emitter and the threshold wavelength are:
- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
The Einstein's equation for photoelectric effect : KEmax=hcλ-W where,W= work function of metal, λ= wavelength of incident light. If V0 be the stopping potential, then KEmax=eV0 So, eV0=hcλ-W…
