Question

Light hits a clear plastic bottle and a granite rock. Which choice most accurately describes the effect of visible light on the clear plastic and a grey rock?
1. Visible light is absorbed by both the rock and the plastic, making both objects warmer. Visible light is also reemitted by both objects, allowing visible light through the rock and the plastic.

2. Visible light is absorbed by both the rock and the plastic, making both objects warmer. Some of the light hitting the rock is reemitted, allowing visible light through the rock. None of the light hitting the plastic is reemitted.

3. Visible light is absorbed by the rock, making it warmer. Light is also absorbed by the plastic making it warmer. None of the light hitting either object is reemitted.

4.Visible light is absorbed by the rock and the plastic making both objects warmer. Some of the light hitting the plastic is reemitted, allowing visible light through the plastic. None of the light hitting the rock is reemitted.

Answer 1

Answer:

#4 is the accurate answer.

Answer 2

Answer:

4

Explanation:

When the light hits an object, it is absorbed, and the energy of it is transferred by the object by heat, thus it warms. When the object is dark the light is not reemitted because the absorption factor of dark color is almost 100%. But, for clear objects, the absorption factor is small, does, some of the light must be reemitted through it.
