In the photoelectric effect, what happens to the emitted electrons if the frequency of the incident light is just at the threshold frequency?

In the photoelectric effect, what happens to the emitted electrons if the frequency of the incident light is just at the threshold frequency?

Step 1: Understand that the photoelectric effect involves light hitting a material and causing electrons to be emitted.
Step 2: Know that light is made of particles called photons, which have energy based on their frequency.
Step 3: Recognize that each material has a specific energy level called the work function, which is the minimum energy needed to release an electron.
Step 4: Identify the threshold frequency as the frequency of light where the energy of the photons is just enough to equal the work function.
Step 5: Realize that when the frequency of the incident light is at the threshold frequency, the energy of the photons is exactly equal to the work function.
Step 6: Conclude that the emitted electrons will have zero kinetic energy because all the energy from the photons is used to overcome the work function, leaving no extra energy for movement.
