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 parallel to the axis refracts outward, as if it came from the focus on the left hand side.

B.
A ray incident on a path that would take it through the right focus refracts parallel to the axis.

C.
A ray incident through the vertex continues through the lens without refracting.

D.
A ray incident parallel to the axis refracts so that it passes through the focus on the right hand side.

The image shows a pendulum in simple harmonic motion the pendulum starts at a and swing to e
