In the diagram below, two of the three rays used to find the image position are shown. Which of the following best describes the third (missing) ray?

A. A ray incident on a path that takes it through the left focus reffects
parallel to the axis.
B. A ray incident through the vertex continues through the lens
without refracting
C. A ray incident parallel to the axis refracts so that it passes through
the focus on the right hand side.

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
