GCSE Physics - How to Draw Ray Diagrams #70

The video tutorial explains how to draw ray diagrams for concave and convex lenses. It starts with concave lenses, describing their diverging nature and how to represent them in diagrams. The process involves drawing incident rays and determining the image's position, which is always virtual and upright. The tutorial then covers convex lenses, which converge light to a point. It explains how to draw ray diagrams for these lenses, noting that the image can be real, inverted, and vary in size depending on the object's distance from the lens. The video emphasizes understanding these concepts for exams.
