SSS3 Physics - Photoelectric Effect

Summary
After this lesson, students will be able to:
Define photoelectric effect, define and describe all three type of photoelectric effects and determine the meaning of symbols, key terms, and other domain-specific words and phrases as they are used in a specific scientific or technical context relevant to this topic.

About
The photoelectric effect is a phenomenon that occurs when light shined onto a metal surface causes the ejection of electrons from that metal. It was observed that only certain frequencies of light are able to cause the ejection of electrons. If the frequency of the incident light is too low (red light, for example), then no electrons were ejected even if the intensity of the light was very high or it was shone onto the surface for a long time. If the frequency of the light was higher (green light, for example), then electrons were able to be ejected from the metal surface even if the intensity of the light was very low or it was shone for only a short time. This minimum frequency needed to cause electron ejection is referred to as the threshold frequency.

Learning Objectives
After this lesson, students should be able to explain:
What are the properties of a photon?
What does the photoelectric effect show about the properties of light?
How does the frequency of light affect the release of photons?
The interaction of light and electrons graphically.
And practice controlling their virtual lab work thoughtfully.
Their results in mathematically precise language.
How the wave model of light is deficient.
And nominate alternate models to fully describe the interaction of light and electrons.
