Question

4)If light is acting like a particle, then what should you adjust in the simulation to

make faster-moving electrons leave the metal surface

Answer 1

To make faster-moving electrons leave the metal surface, increase the frequency of light in the photoelectric effect simulation.

Step-by-step explanation:

If light is acting like a particle and you want to make faster-moving electrons leave the metal surface in a simulation of the photoelectric effect, you should adjust the frequency of the light. According to Einstein's explanation of the photoelectric effect, it's the energy of the photons (which is directly proportional to their frequency) that determines the kinetic energy of the ejected electrons. Thus, to make electrons move faster once ejected, you would need to increase the frequency of the light, so long as it's above the characteristic threshold frequency for the specific metal being simulated.

Answer 2

We can either increase the frequency of the light source or decrease the wavelength of the light source in the simulation

Step-by-step explanation:

When light approaches or strike a metal surface, we can observe electrons coming out the metal surface. So, when a light wave hits a metal surface, it becomes protons; thus, we can either increase the frequency of the light source or decrease the wavelength of the light source in the simulation.

Thus, a higher energy photon will strike the electron, and the electrons tend to gain energy from the photons.
