or refracted by traveling through another object.

Light does not curve. During reflection and refraction the light either bounces off or bends at an angle, and then
continues traveling in a straight line.

Tell whether the following diagrams represent reflection or refraction. Explain how you know.
Reflection; The light is bouncing off the object, not passing through the object.

Refraction; The light is passing through an object and changing its direction.

Reflection; The light is not traveling through an object. It is bouncing off the object.

A student placed a pencil in a glass of water. The pencil appears broken because light –
A always travels in a straight line.
B makes the water in the glass evaporate.
C bends when it passes through water.
D reflects the pencil on the water’s surface.
C ~ bends when it passes through water.
