The reason that a surface appears darker when wet has to do with
A)the darkness of liquids.
B)conversion of light to lower frequencies.
C)absorption of light re-reflecting inside the wet region.

Question

Quizplus · Accepted Answer

When a surface is wet, the water droplets on its surface absorb some of the light that falls on it. This light is then re-reflected inside the wet region, making the wet area appear darker than the dry surrounding region. This is also why the wet region appears lighter when viewed from an angle, as some of the light that falls on the surface is reflected back. Therefore, Option C, absorption of light re-reflecting inside the wet region, is the correct answer. Option A, the darkness of liquids, is not a relevant factor as the darkness of the liquid does not affect the appearance of the wet surface. Option B, conversion of light to lower frequencies, is also not relevant as there is no change in the frequency of light when it falls on a wet surface.
