Q
Q: What happens to the photoelectric effect if the incident light is below the threshold frequency?
Solution: If the incident light is below the threshold frequency, no electrons are emitted.
Steps: 5
Step 1: Understand the photoelectric effect. This is when light hits a material and causes it to release electrons.
Step 2: Know what threshold frequency means. This is the minimum frequency of light needed to release electrons from the material.
Step 3: Identify the incident light. This is the light that is shining on the material.
Step 4: Compare the frequency of the incident light to the threshold frequency. If the incident light's frequency is lower than the threshold frequency, it cannot release electrons.
Step 5: Conclude that if the incident light is below the threshold frequency, no electrons will be emitted from the material.
