What is Properties of Light in Year 4 Science (KSSR)?
Light is a form of energy that travels in straight lines. This chapter covers the main properties of light: travels in straight lines, can be reflected (mirrors), refracted (prisms, glass), and absorbed by opaque materials.
Chapter Summary
Light is a form of energy that travels in straight lines. This chapter covers the main properties of light: travels in straight lines, can be reflected (mirrors), refracted (prisms, glass), and absorbed by opaque materials. Shadows form when light is blocked by opaque objects, and their size changes with the distance of the object from the light source.
