What type of light can cause materials to get warm?

Back

Infrared light can cause materials to get warm because it carries energy that can be absorbed by the materials.

Front

Why does sunlight dry glue faster than light from a desk lamp?

Back

Sunlight carries more energy that the glue can absorb, allowing it to dry faster.

Front

What happens to special plastic when exposed to sunlight?

Front

What is the role of energy in light waves?

Back

Energy in light waves can cause materials to heat up, change color, or undergo chemical reactions.

Front

Why do some materials not change when exposed to light?

Back

Some materials do not absorb energy from certain types of light, preventing any change.

Front

What is the effect of X-ray light on materials?

Back

X-ray light can penetrate materials and may cause changes, but it does not typically cause heating like infrared light.

Front

How does light from the sun differ from light from a lamp?

Back

Light from the sun is more intense and carries more energy than light from a typical desk lamp.
