A student puts a piece of black paper and a piece of white paper in the same sunny spot. After 30 minutes, the student observes that the black paper feels warmer than the white paper. What is the best explanation for this observation?

• The black paper absorbs more light waves from the sun than the white paper.

• The black paper reflects more light waves from the sun than the white paper.

• The black paper prevents light waves from the sun from reaching the white paper.
