Why it is the frequency and not the intensity of the light source that determines whether the emission of photoelectrons will occur or not? Explain.

उत्तर
The frequency, not the intensity, of the light source, determines the emission because if any incident light of a specific (i.e., threshold or more) frequency is incident, it results in emission regardless of its intensity.
