Expert Film: Jon Badgery demonstrates how lenses can be used to bend and focus light.

This video explores how convex lenses manipulate light by bending it to focus at a single point, known as the focal point, demonstrating the principle of converging lenses. Joe shows a practical trick involving focusing laser light to a tiny point, illustrating how lenses can concentrate energy for applications like laser technology. Learners will understand the behaviour of convex lenses and their ability to focus light precisely.
