Which of the following scientists has not contributed significantly to photoelectric effect ?
- A Wilhelm Hallwachs
- B Philipp Lenard
- C Albert Einstein
- D C.J. Davisson
Answer & Solution
Correct Answer
(D) C.J. Davisson
Step-by-step Solution
Detailed explanation
While Hallwachs, Lenard, and Einstein were all central figures in discovering and explaining the photoelectric effect, C.J. Davisson is famous for the Davisson-Germer experiment. His work demonstrated the wave nature of electrons through diffraction, rather than the particle…
