NEET · Physics · STD 12 - 11. Dual nature of radiation and matter
Light of frequency \(1.5\) times the threshold frequency Is incident on a photosensitive material. What will be the photoelectric current if the frequency is halved and intensity is doubled\(?\)
- A \(0\)
- B doubled
- C four times
- D one-fourth
Answer & Solution
Correct Answer
(A) \(0\)
Step-by-step Solution
Detailed explanation
\(K _{1}=1.5 hv _{0}-\phi_{0}=0.5 hvo\) \(K _{2}=\frac{1.5}{2} h { v }_ 0- h v_ 0=-0.25 h v_{ 0}\)
