Photoelectric effect
Question:

Photovoltaic is an applied technology for the utility of solar energy, which covers the conversion of light into electricity using metal materials that exhibit the photoelectric effect.

The photoelectric effect is a   phenomenon that when an electron attains a proportional energy from sunlight which exceeds the limitation of the energy barrier which is hinged upon the material of metal plates, it can jump over the energy barrier, get out of itself metal plate and reaches another metal plate, and further produce current flows.

Now let’s play with the simulation and research some interesting relationship between two parameters.
in the animation you have two slides in the upper right corner. The first one is about the intensity of the light and the other one shows the spectrum of the light.
play with the simulation and answer the question below.

 




Which of the following is correct?

When the wavelength decreases the amount of the emitted electrons decreases. The amount of the emitted electrons is proportionally inverse to the intensity of light.

When the wavelength increases the amount of the emitted electrons decreases. The amount of the emitted electrons is proportional inverse to the intensity of light.

When the wavelength increases the amount of the emitted electron decreases. The amount of the emitted electrons is proportionally related to the intensity of light.

When the wavelength increases the amount of the emitted electrons increases. The amount of the emitted electrons is proportionally related to the intensity of light.

remember the mathematical relationship between the energy of light and the wavelength. E=c/w.
the increase of the intensity of light increases the number of the emitted electrons.

remember the mathematical relationship between the energy of light and the wavelength. E=c/w.
the increase of the intensity of light increases the number of the emitted electrons.
