NEET Physics Photoelectric Effect MCQ Question
Which of the following combinations correctly describes the features of the photoelectric effect?
Photoelectric current increases with light intensity; minimum frequency is required for emission.
Photoelectric effect occurs regardless of light frequency; stopping potential increases with intensity.
Only ultraviolet light can cause photoelectric emission; current is proportional to frequency.
Kinetic energy of emitted electrons is independent of light frequency; photoelectric effect is a slow process.
Correct Answer
Detailed Explanation
The photoelectric current does depend on the intensity of incident light and requires a minimum frequency for electron emission, as highlighted in the NCERT context.
