Mystery Hour Question
Why do wet things look darker?
** Definitive **
Name: Kevin, Cambridge
Qualification: In my computer and game programming degree we had to write programme for wet surfaces
Answer: Every surface reflects light. When a porous surface becomes wet the light gets trapped between the water layer and the surface layer. Less light is being reflected which makes the object appear darker.
