Light Waves Review

Light energy is a form of energy that travels in waves and can be seen by the human eye. It is responsible for the colors we see and can cause changes in materials, such as color changes in special nail polish.

A wave crest is the highest point of a wave. It is the point where the wave reaches its maximum height.

All waves carry energy.

Amplitude is the height of a wave from its rest position to its crest. It measures the energy of the wave; greater amplitude means more energy.

Sunlight can provide energy to materials, causing changes such as color change in special nail polish or drying glue.

Sunlight contains a broader spectrum of light and more energy compared to the light from a desk lamp, which may not provide enough energy for certain reactions.

Energy is what allows waves to cause changes in materials, such as heating, moving, or altering their state.

When light hits an object, it can be reflected, absorbed, or transmitted, depending on the properties of the object.

Reflection is the bouncing back of light waves when they hit a surface that does not absorb the light.

Absorption is the process by which an object takes in light energy, which can lead to changes in temperature or state.
