Question

Photoelectric effect is not possible for the light of all frequencies. (T/F)

Hint:

The photoelectric effect occurs only when the frequency of light exceeds a threshold frequency, which depends on the material.

Answer 1

Step 1: Understanding the concept.
The photoelectric effect only occurs when the frequency of the incident light is above a certain threshold frequency. Light with lower frequencies (below the threshold frequency) cannot cause the ejection of electrons from a material, regardless of its intensity.
Step 2: Analyzing the statement.
The statement is True, as the photoelectric effect requires a minimum frequency of light to eject electrons from a surface.
Step 3: Conclusion.
The correct answer is True, as the photoelectric effect does not occur for all frequencies of light.
