Question: What is the relationship between the frequency of incident light and the number of emitted electrons in the photoelectric effect?

Options:

Correct Answer: No relationship

Solution:

The number of emitted electrons is related to the intensity of light, not the frequency, as long as the frequency is above the threshold.

What is the relationship between the frequency of incident light and the number of emitted electrons in the photoelectric effect?

Step 1: Understand the photoelectric effect. This is when light hits a material and causes it to emit electrons.
Step 2: Know that light has two important properties: frequency and intensity.
Step 3: Frequency is how fast the light waves oscillate, while intensity is how much light is present.
Step 4: There is a minimum frequency called the 'threshold frequency' that light must have to emit electrons.
Step 5: If the frequency of the light is below this threshold, no electrons will be emitted, regardless of the intensity.
Step 6: If the frequency is above the threshold, electrons will be emitted.
Step 7: The number of emitted electrons depends on the intensity of the light, which means more light (higher intensity) can cause more electrons to be emitted.
Step 8: Therefore, as long as the frequency is above the threshold, increasing the intensity (not frequency) will increase the number of emitted electrons.
