Introduction to Reflection in Spherical Mirrors

The video tutorial explores the concept of reflection, focusing on spherical mirrors. It introduces real-life examples of spherical mirrors, such as spoons, and explains how they differ from plane mirrors. The tutorial covers technical terms like center of curvature, radius of curvature, pole, principal axis, focus, and focal length. It also discusses the behavior of light in concave and convex mirrors, highlighting the differences between real and virtual focus. The session concludes with a thought-provoking question about reflections in curved mirrors, setting the stage for future lessons.
