Question 1
Which options represent correct variation of photoelectric current vs. property on x-axis?
  • A and D✔️
  • B and D
  • A only
  • A and C
Correct Answer Explanation
Photoelectric current vs. intensity: linear (proportional) — Graph A is correct (linear through origin). Photoelectric current vs. frequency: zero below threshold, then increases above — Graph D shows this (starts from threshold). B (flat vs intensity) and C (linear from zero vs frequency) are incorrect. Correct: A and D.
