Class 7 Science Chapter 11 | Light: Shadows and Reflections | CBSE NCERT New

Master Chapter 11 “Light: Shadows and Reflections” in one go—full NCERT Curiosity explanation with solutions, diagrams, mind map, MCQs, and important questions. Rectilinear propagation of light, shadow formation (umbra/penumbra), pinhole camera, reflection of light, plane mirrors, image formation, virtual image, erect image, lateral inversion, regular vs. diffused reflection—explained with simple examples for exams. What you will learn! How light travels in a straight line (Rectilinear Propagation). 💡 How shadows are formed (umbra and penumbra) and what's needed to make one. How a simple pinhole camera works and forms an inverted image. The law of reflection and the difference between regular (smooth) and diffused (rough) reflection. Properties of an image formed by a plane mirror: virtual, erect, same size, and laterally inverted (left appears right).
