What is reflection, and how does it allow us to see objects?

Reflection is when light bounces off a surface. It allows us to see objects because the reflected light enters our eyes.

Explain the difference between reflection from a smooth surface like a mirror and a rough surface like a wall.

A smooth surface reflects light evenly, creating a clear image. A rough surface scatters light in many directions, so no clear image is formed.

Absorption is when light energy is taken in by a material. The light energy is converted into heat.

A black shirt absorbs most of the light energy, converting it to heat, while a white shirt reflects more light away.

The red shirt absorbs all colors of light except red, which is reflected. The reflected red light is what we see.

I can describe how light interacts with different materials.

1
When light bounces off a surface, it is called reflection, and the angle at which it hits the surface is the same as the angle at which it leaves.
2
Absorption occurs when light's energy is taken into a material as heat, which is why a black shirt feels warmer than a white shirt.
3
Refraction is the bending of light as it passes through different mediums due to changes in speed, which is why objects in water may appear bent.
