RET Teaching Module 25: Photoelectric Effect:  Particle Nature of Light Evidence

Overview

This module starts with describing the research experience conducted by the teacher on 2D TMDC’s (Transition Metal Dichalcogenides) for electronic and photonic devices and relate this to one of the evidences on the particle nature of light - photoelectric effect which takes place when an incident light is shone on metal and electrons are liberated. Students will investigate the concepts behind the photoelectric effect using an interactive simulation, a hands-on activity where they build a model that demonstrate this light phenomenon. Through these, students developing understanding on the role of light frequency and intensity in the photoelectric effect. Lastly, students will be introduced into an extension activity where they create a light alarm using the Arduino interface and the SunFounder Uno. The lesson concludes with a summative assessment of the evidence for light's dual nature.

After completing this module, student should be able to:

• Investigate the particle nature of light energy
• Build a model of the Photoelectric effect
• Make a light alarm using SunFounder UNO and Arduino interface
