When a black brick is placed in direct sunlight, its temperature rises. This rise in temperature BEST demonstrates which of the following?

• Energy from the Sun is transferred by waves to the brick by refraction.
• Energy from the Sun is transferred by waves to the brick by reflection.
• Energy from the Sun is transferred by waves to the brick by absorption.
• Energy from the Sun is transferred by waves to the brick by gravitational force.

Back

Energy from the Sun is transferred by waves to the brick by absorption.
