Click the ALL the reasons for the appearance of the man's eye in the picture.

• Magnification by the observation tool.

• Refraction through the observation tool.

• Reflection off the observation tool.

• Light moving in straight lines.

Some students shined a light through a hole in a piece of cardboard. They saw a narrow beam of light continue until another student put a mirror in the light's path.

The light did not continue past the mirror because...

• Light cannot travel 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.
