Light and Sound

Light

Light is a form of energy that allows us to see things. It is made up of tiny particles called photons. Light travels in straight lines and at a very fast speed.

Properties of Light

1. Reflection: Light bounces off a surface.
2. Refraction: Light bends when it passes through different materials.
3. Absorption: Some materials absorb light, while others reflect it.

Sound

Sound is a form of energy produced by vibrations. These vibrations travel through the air as sound waves and can be heard by our ears.

Properties of Sound

1. Pitch: How high or low a sound is.
2. Volume: How loud or soft a sound is.
3. Amplitude: The size of the sound waves, which determines the volume.

How They Interact

Light and sound can both be absorbed, reflected, or refracted. For example, when light hits an object, it can be absorbed or reflected, and when sound waves encounter different materials, they can be absorbed or reflected as well.
