In the experimental arrangement for study of photoelectric effect given below, P, Q, R and S, respectively are
(A) Commutator
(B) Evacuated Glass Tube
(C) Photosensitive Plate
(D) Quartz Window
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → (D), (B), (A), (C)
$\text{P: light enters through window} \Rightarrow \text{Quartz window}$
$\text{Q: outer enclosure} \Rightarrow \text{Evacuated glass tube}$
$\text{R: switching device} \Rightarrow \text{Commutator}$
$\text{S: emitting surface} \Rightarrow \text{Photosensitive plate}$
P = Quartz Window, Q = Evacuated Glass Tube, R = Commutator, S = Photosensitive Plate.
