Chapter 5: Properties of Light
What you need to learn in this chapter
In this chapter, we will learn about the properties of light.
We will discover that light travels in a straight line by doing activities.
We will also compare and contrast the shadows formed when light is blocked by transparent, translucent, and opaque objects.
Next, we will explore the reflection of light.
We will learn that light can be reflected by doing activities.
We will also discuss the uses of reflection of light in our daily lives.
Lastly, we will study the refraction of light. We will observe how light can be refracted through different media.
We will also learn that light can be refracted by doing activities and examples will be given to explain this concept.
