Why doesn’t the surface of a wooden boat reflect light as the surface of water does?
Because the boat's surface is rough and absorbs more light.
Because the surface of the boat is red, not blue.
Because the boat is not a natural object like the water is.
Because the boat is on top of the water's surface.
What is the angle of incidence?

The angle at which light is absorbed by an object.
The angle at which light bounces off a surface.
