CBSE BoardEnglish MediumSTD 12 SciencePhysics11. Dual nature of radiation and matter1 Mark
MCQ
As the intensity of incident light increases
  • ✓
    Photoelectric current increases
  • B
    Photoelectric current decreases
  • C
    Kinetic energy of emitted photoelectrons increases
  • D
    Kinetic energy of emitted photoelectrons decreases
✓

Answer

Correct option: A.
Photoelectric current increases
a
(a)Intensity increases means more photons of same energy will emit more electrons of same energy, hence only photoelectric current increases.
