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.

• Light waves don’t travel in a straight line.

• Light waves travel in a straight line because sound waves travel in a straight line.

What is it called when light bends as it moves from one substance to another?

• absorption

• reflection

• refraction

• incidence

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
