 Photoelectric Effect PhET Lab

 

Name: ___________________________________________________

 

Open the Photoelectric Effect PhET Simulation. **Before adjusting anything answer the questions below**

 

1) Before you begin, what do will happen to …

 

a) the metal surface when light strikes it

 

b) the light the intensity slider is moved

 

2) Do you think all intensities of light will liberate electrons? Explain.

 

3) Do you think all wavelengths of light will liberate electrons? Explain.

 

Part 1 – Intro to Photoelectric Effect   

 

1) What can you change in the simulation?

 

2) Select a metal to study. Develop a procedure for determining the characteristics of the light necessary to liberate electrons from the metal. Write your procedure and your conclusions below.

 

3) Based on your chosen metal answer the following questions

 

a) At what wavelengths was it first possible to remove electrons?

 

b) What wavelengths were most effective?

 

c) What does intensity change?

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Part II – Finding a Model for the Photoelectric Effect

 

4) Describe the three graphs you can view in the simulations by filling in the table below.

 

Graph

Relationship

Explanation (using physics terms)

Current vs. Battery Voltage

 

 

Current vs. Light Intensity

 

 

Electron Energy vs. Light Frequency

 

 

 

5) Propose a mathematical equation for the photoelectric effect using the terms we have discussed in class (work function, incident light, max E of ejected electrons). Use the simulation to verify your model and make a graph of the maximum electron energy vs. the light frequency.
