NEET Physics Photoelectric Effect MCQ Question
Consider a diagram showing a metal surface being irradiated with light of varying frequencies. Label the threshold frequency (f₀) where no electrons are emitted. Which metal property determines this threshold frequency?

Work function of the metal
Conductivity of the metal
Atomic mass of the metal
Density of the metal
Correct Answer
Detailed Explanation
The threshold frequency depends on the work function of the metal, which is the minimum energy needed to emit electrons, as described in the NCERT context.
