Key Concepts Reviewer: Science Grade 10 – Lenses and Mirrors 1. Reflection of Light o Light bounces off a surface. o Laws of Reflection: ▪ The angle of incidence = angle of reflection. ▪ Incident ray, reflected ray, and normal lie in the same plane. 2. Refraction of Light o Bending of light when passing between different media (e.g., air to glass). ▪ n: Refractive index. o Speed of light changes in different media. 3. Types of Mirrors o Plane Mirror: ▪ Forms virtual, upright, and same-sized images. o Spherical Mirrors: ▪ Concave Mirror: ▪ Can form real or virtual images depending on the object's position. ▪ Used in telescopes, headlights. ▪ Convex Mirror: ▪ Forms virtual, upright, and diminished images. ▪ Used as security or rear-view mirrors. 4. Mirror Equations and Magnification o Mirror Formula: ( see page 190-191 ) o Magnification: ▪ M>1M > 1M>1: Enlarged image, M
