WASSCE 2023 PHYSICS PRACTICAL ALT A QUESTION 2 - LIGHT

In this informative video, we will guide you through a Class 12 physics practical experiment aimed at determining the focal length of a convex lens. We will use a ray box, a convex lens and lens holder, a meter rule, and a screen to perform this experiment step by step. First, we will explain the setup and arrangement of the apparatus. Next, we'll demonstrate how to conduct the experiment and make precise measurements using the meter rule. One of the crucial steps in this experiment is plotting a graph, we'll illustrate how the graph can be plotted. We will also discuss the precautions necessary to ensure accurate results. We will emphasize the importance of handling the equipment carefully, minimizing parallax errors, and ensuring the lens is clean and free from dust. By the end of this video, you will have a comprehensive understanding of how to determine the focal length of a convex lens through this practical experiment, and you will be well-prepared for your Class 12 physics examination. Good luck with your experiments!
