🌟 Light Absorption, Reflection, and Transmission

Introduction

When light hits an object, three things can happen:

1. Absorption – the object takes in the light.

2. Reflection – the light bounces off the object.

3. Transmission – the light passes through the object.

These processes help us see things and explain why objects look different colors.

Explanation + Examples

1. Absorption

   • Light is taken in by the material.

   • The absorbed light often changes into heat.

   • Example: Wearing a black T-shirt in summer feels hotter because it absorbs most of the sunlight.

2. Reflection

   • Light bounces back from the surface.

   • This is why we can see ourselves in mirrors.

   • Example: A mirror reflects almost all the light that hits it.

3. Transmission

   • Light passes through the object.

   • Can be transparent (clear, like glass) or translucent (lets some light through, like frosted glass).

   • Example: Window glass transmits light so we can see outside.

Comparison Table

Process	What happens	Example
Absorption	Light is taken in (becomes heat)	Black shirt, solar panels
Reflection	Light bounces off surface	Mirror, shiny metal, calm water
Transmission	Light passes through material	Glass window, plastic bottle

Illustration (Easy to Imagine)

☀️ Light → hits BLACK T-shirt → absorbed → feels hot (Absorption)

☀️ Light → hits MIRROR → bounces back → we see reflection (Reflection)

☀️ Light → hits GLASS → passes through → we see outside (Transmission)

---

✅ Summary :

• Absorption: Light is soaked up (black clothes, solar panels).

• Reflection: Light bounces back (mirrors, shiny surfaces).

• Transmission: Light goes through (glass, clear plastic).
