Consider the two following statements I and II, and identify the correct choice given in the answers
III. In photovoltaic cells the photoelectric current produced is not proportional to the intensity of incident light.
IV. In gas filled photoemissive cells, the velocity of photoelectrons depends on the wavelength of the incident radiation.
III. In photovoltaic cells the photoelectric current produced is not proportional to the intensity of incident light.
IV. In gas filled photoemissive cells, the velocity of photoelectrons depends on the wavelength of the incident radiation.
View answer and explanation
Correct option: D
I is false but II is true
Option D (I is false but II is true) is correct because the photoelectric current is proportional to the intensity of light, and the velocity of photoelectrons in gas-filled cells does depend on the wavelength.
