In a photoelectric effect experiment, increasing the intensity of light increases the number of emitted electrons. What does this imply?
Light is a wave
Light is a particle
Energy of each photon increases
Number of photons increases
Increasing the intensity of light increases the number of photons hitting the surface, which in turn increases the number of emitted electrons.

Q
Q: In a photoelectric effect experiment, increasing the intensity of light increases the number of emitted electrons. What does this imply?
Solution: Increasing the intensity of light increases the number of photons hitting the surface, which in turn increases the number of emitted electrons.
Steps: 6
Step 1: Understand that light is made up of tiny particles called photons.
Step 2: Realize that when light shines on a surface, these photons can hit the surface.
Step 3: Know that when a photon hits an electron in the surface, it can give the electron enough energy to escape.
Step 4: Increasing the intensity of light means more photons are hitting the surface at the same time.
Step 5: More photons hitting the surface means more chances for electrons to be hit and emitted.
Step 6: Therefore, increasing the intensity of light leads to an increase in the number of emitted electrons.
