What might explain why light travels in a straight line?
If there is nothing to interfere with light waves, they should travel in a straight line.
Light waves will always travel in a straight line, even if they come into contact with another object.

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 diffuses 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 bends in water
the angle at which light hits a surface
the angle at which light is absorbed by an object
the angle at which light bounces off a surface
