What is the effect of increasing the intensity of light on the energy of emitted electrons in the photoelectric effect?
It increases the energy
It decreases the energy
It does not affect the energy
It can either increase or decrease the energy
Increasing the intensity of light increases the number of emitted electrons but does not affect their energy, which depends on the frequency.

Q: What is the effect of increasing the intensity of light on the energy of emitted electrons in the photoelectric effect?
Solution: Increasing the intensity of light increases the number of emitted electrons but does not affect their energy, which depends on the frequency.
Steps: 6
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 intensity and frequency. Intensity is how bright the light is, and frequency is how many light waves pass a point in a second.
Step 3: Realize that increasing the intensity of light means more light waves are hitting the material.
Step 4: When more light waves hit the material, more electrons can be emitted because there are more chances for the light to interact with the material.
Step 5: However, the energy of the emitted electrons depends on the frequency of the light, not the intensity. Higher frequency light gives electrons more energy.
Step 6: Therefore, increasing the intensity increases the number of emitted electrons but does not change their energy.
