Do you know the difference between virtual and real images formed by lenses? This activity will answer that question through easy hands-on activities and will compare the Galilean telescope with the Keplerian telescope. You can access the tutorial plus others at lightlabetc.com/extra-activities.
We also invite you to watch The Blessings of Vision to learn how your eyes see and how glasses correct vision problems. At the end of the video, we refer to Acts 8-9, which tells the story of the Apostle Paul’s conversion. A detailed study of these chapters is found in our book, Lightlab, in chapter 8, “Focus on the Light!”
