For a class demonstration a student turned off the lights in the classroom. The student then shined light from a flashlight through a hole in a piece of cardboard. The class saw the narrow beam of light continue until another student placed a mirror in the light's path. The light did not continue past the mirror because -

• light cannot travel very far

• the mirror absorbed all the light

• the light was refracted back to the light source

• light travels in a straight line and cannot go around objects
