Light, Shadows and Reflection

Light is a form of energy that enables us to see objects. It travels in straight lines and at an extremely high speed. Objects that emit their own light are called luminous objects, like the sun and bulbs, while objects that do not emit light are non-luminous, like the moon and furniture. When light falls on an opaque object, it cannot pass through, creating a dark area called a shadow. Shadows are formed because light travels in straight lines. This Light, Shadow, and Reflection Class 7 Quiz explores these optical phenomena and how light behaves with different surfaces. Reflection is the bouncing back of light when it strikes a surface. Mirrors reflect light and form images. Smooth surfaces cause regular reflection, while rough surfaces cause diffuse reflection. Learning about light, shadows, and reflection helps students understand optical phenomena and how we perceive the world. Take these 10 questions to test your knowledge.
