A student placed a pencil in a cup of water.  The pencil appears broken because light-

• always travels in a straight line
• bends when it passes through water
• makes the water in the glass evaporate
• reflects the pencil on the water's surface

What does it mean to refract?

• bounce off
• to bend
• curve outward
• reflect

movement of particles in waves through space or other medium (surrounding material; air, water)

• Reflection

the slow movement (wobble) of the axis of a spinning body around another axis (due to gravitational influence) acting to change the direction of the first axis.

• Eccentricity
• Precession
• Obliquity

rising and falling, usually irregular / not a consistent pattern

• Fluctuation
• Proximity
• Insolation
• Graphing

"angle" measuring Earth's geographic coordinates from the Prime Meridian, 0, to east or west +/- 180 degrees respectively.
