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

Options:

Correct Answer: Directly proportional

Solution:

The number of emitted electrons is directly proportional to the intensity of light, provided the frequency is above the threshold frequency.

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

Correct Answer: The number of emitted electrons increases with the intensity of light.

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 both intensity and frequency. Intensity is how bright the light is, and frequency is related to the color of the light.
Step 3: Learn about the threshold frequency. This is the minimum frequency of light needed to emit electrons from the material.
Step 4: If the frequency of the light is above the threshold frequency, the light can cause electrons to be emitted.
Step 5: The intensity of the light affects how many photons (light particles) hit the material. More photons mean more chances to emit electrons.
Step 6: Therefore, if the intensity of the light increases (while keeping the frequency above the threshold), more electrons will be emitted.
Step 7: Conclude that the number of emitted electrons is directly proportional to the intensity of light, as long as the frequency is sufficient.
