Q
Q: Which of the following statements is true about the photoelectric effect?
Solution:
The photoelectric effect requires a minimum frequency of light known as the threshold frequency.
Steps: 5
Show Steps
Step 1: Understand that the photoelectric effect is a phenomenon where light can cause electrons to be emitted from a material.
Step 2: Learn that not all light can cause this effect; only light with a certain minimum frequency can do so.
Step 3: This minimum frequency is called the threshold frequency.
Step 4: If the frequency of the light is below this threshold, no electrons will be emitted, regardless of the light's intensity.
Step 5: If the frequency is above the threshold, electrons will be emitted, and their energy will depend on the frequency of the light.
