Getting Ready for OAPT using the PASCO Basic Optics System

This past week we got to work with the PASCO Basic Optics System, OS-8515C. Using components of the kit, we were able to try out some introductory optics experiments. To start off, we used the Ray Table, the D-Shaped Lens, and the Light Source to perform a simple refraction experiment, using the PASCO Refraction lab as guidance as shown in the image on the left. This experiment was very easy to set up. All you need to do is plug in the Light Source and follow the instructions in the Refraction lab document. This experiment explores Snell’s Law, describing the relationship between angles of incidence and refraction.

We also conducted the PASCO Virtual Images lab which involved the use of the PASCO Optics Track, Light Source, Lenses, and Viewing Screen. This allowed us to make observations on the virtual image produced by the light source and lenses. By going through this lab, we made multiple observations, for instance, when using the -150 mm concave lens and looking through it the image is upright, smaller, and closer to the lens than the object. When we add the +200 mm convex lens between the concave lens and the screen, a real image is formed on the screen mirrored, inverted, and smaller. After removing the concave lens, the image remained mirrored, inverted, and the image became blurry. The Light Source had to be moved closer to the screen for the image to become clear. We found this lab to be very interesting, making use of many of the components from the Basic Optics System and expanding our knowledge of optics.
