Reflection

Reflection is the process by which light, sound, or heat is returned from a surface without being absorbed. When light, sound, or heat strikes a surface, it can be reflected, absorbed, or transmitted. Reflection occurs when the surface is smooth and the light, sound, or heat is not able to pass through the surface.

Types of Reflection

There are two main types of reflection: regular reflection and diffuse reflection.

• Regular Reflection: Occurs when light, sound, or heat is reflected from a smooth and shiny surface, such as a mirror.
• Diffuse Reflection: Occurs when light, sound, or heat is reflected from a rough or uneven surface, such as a piece of paper or a wall.

Study Guide

Here are some key points to remember about reflection:

1. Reflection is the process by which light, sound, or heat is returned from a surface without being absorbed.
2. Regular reflection occurs from a smooth and shiny surface, while diffuse reflection occurs from a rough or uneven surface.
3. Reflection is an important concept in understanding how we see objects and how we hear sounds.
4. Understanding reflection can help us design and create reflective surfaces, such as mirrors, for various purposes.

Remember, understanding reflection is important in the study of light, sound, and heat, and it has many practical applications in our everyday lives.
