Convex vs Concave Lenses Explained in 5 Minutes | Animated Physics

Confused about convex and concave lenses? This 5-minute animated lesson explains lenses step by step, with moving ray diagrams, so you can see how each type bends light. What you'll learn: What a lens is (an optically transparent medium bounded by spherical refracting surfaces) Convex (bi-convex) lens: thicker at the centre, converges light to a focus Concave (bi-concave) lens: thinner at the centre, diverges light Plano-convex and plano-concave lenses, and how they differ A quick way to remember: convex converges, concave diverges Chapters: 0:00 Introduction 0:20 What is a lens? 1:05 Two main types of lenses 1:20 Convex lens 2:25 Concave lens 3:30 Other types of lenses (plano-convex and plano-concave) 4:25 Recap Perfect for school students revising the "Lenses" topic in the optics chapter of their physics syllabus, and for anyone curious about how spectacles, cameras, microscopes and telescopes work.
