Q Lens Lab Today, you will use Geometric Optics PhET Lab to investigate the properties of converging lenses and verify the lens equation. The equations on the lab are a little different from the lecture equations. They are the same, just using different variables. do = O = Object distance dI = I = Object distance Part 1 – Beginning Observations 1) Open the Geometric Optics PhET simulation. https://phet.colorado.edu/sims/html/geometric-optics/latest/geometric-optics_en.html What can you change about the simulation? 2) The little “x” is the focal point. What are the three places you can put the pencil and what are the characteristics of the image? **hint you may need to click “virtual image” Placement – draw a picture Characteristics of Image Real/virtual 1 - 2 - 3 - Part 2 – Verify the Lens Equation Now, you will verify the lens equation by keeping the characteristics of the lens constant and changing the image distance. Write your procedure below, record your results, calculate the magnification, indicate if the image is real/virtual and write a brief conclusion. Below are the equations you may need.
