Class 8 Science Chapter 10, Light: Mirrors and Lenses, starts with Meena looking into curved mirrors at a science centre, then investigates concave and convex spherical mirrors, the laws of reflection, and convex and concave lenses.
What Class 8 Science Chapter 10 Covers
10.1 What Are Spherical Mirrors? and 10.2 Characteristics of Images introduce concave and convex mirrors with a shiny spoon and curved mirrors (Activities 10.1 to 10.3), along with their uses in torches, dental mirrors and vehicle side-view mirrors.
10.3 What Are the Laws of Reflection? verifies through ray-box and pin experiments (Activities 10.4 to 10.7) that the angle of incidence equals the angle of reflection and that the incident ray, normal and reflected ray lie in the same plane.
10.4 What Is a Lens? explores converging (convex) and diverging (concave) lenses and the images they form (Activities 10.8 to 10.11).

FAQ
Why do vehicle side-view mirrors say ‘Objects in mirror are closer than they appear’?
Side-view mirrors are convex mirrors, which give a wider field of view by forming erect, diminished images that make objects appear further away.
What are the two laws of reflection in Class 8 Science Chapter 10?
First, the angle of incidence is equal to the angle of reflection; second, the incident ray, the normal at the point of incidence, and the reflected ray all lie in the same plane.
