What is the main reason light from different sources can have different effects on materials?

Back

Sources can emit different types of light.

Front

In order for light to change an object, what must that object do with the light?

Back

Reflection is when light bounces off an object, while absorption is when light is taken in by the object.

Front

What is the wavelength of light?

Back

The distance between two consecutive peaks of a wave.

Front

What is amplitude in the context of light waves?

Back
