What is reflection?

  • Definition of Reflection: Reflection is a phenomenon involving the interaction between light and surfaces.
  • Basic Concept: When light encounters a surface, it bounces off in different directions.

Key Points about Reflection

  • Light Behavior: Light travels and can bounce off surfaces, such as mirrors or other objects.
  • Surface Impact: The nature of a surface affects how much light is reflected - smooth and shiny surfaces reflect well, while dull and dark surfaces absorb light.
  • Angle of Reflection: Light bounces off a surface at the same angle at which it hits the surface.
  • Application in Everyday Life: Reflection is why we see ourselves in mirrors and why different materials appear the way they do under light.

Examples of Reflection

  • Mirrors: Mirrors reflect light effectively due to their smooth and polished surfaces.
  • Dark Surfaces: Dark fabrics absorb light, making them appear less reflective compared to shiny surfaces.

Importance of Reflection

  • Visibility: Reflection helps us see objects by bouncing light into our eyes.
  • Design: Understanding reflection is crucial in designing various surfaces and materials for specific purposes.

How reflection works?
