Select all the TRUE statements:

• Darker colored objects absorb light energy.

• Lighter colored objects absorb less energy.

• Black pavement would be hotter than white side sidewalk.

• Lighter clothes would keep you cooler than darker clothes.

What detail in the article shows HOW scientists group different kinds of light energy?

• The electromagnetic spectrum includes light we can see. It also includes light we cannot see.

• Visible light is the type of light we can see. It includes the colors that we can see with our eyes.
