Which answer is true about dark-colored surfaces? PLEASE HURRY ITS DUE NOW
jarptica [38.1K]

Option D is correct. The truth about dark-colored surfaces is Dark-colored surfaces absorb more visible light than light-colored surfaces.

<h3>What is meant by the absorption of light?</h3>

The process by which light is absorbed and transformed into energy is known as light absorption. Plants' photosynthesis serves as an illustration of this procedure. However, not only plants, but all living things and inorganic materials, absorb light.

While absorbed light is the source of energy that powers processes in the atmosphere, hydrosphere, and biosphere, reflected light bounces back into space.

Absorption: This occurs when light is changed into a different kind of energy. When light vanishes as it travels through another medium, something happens.

When light is absorbed, an item becomes black or opaque to the incoming wave's colors or wavelengths: It is impossible to see through wood. Some substances are transparent to some light wavelengths but opaque to others. Water and glass are transparent to visible light but opaque
