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

Answer:

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

Step-by-step explanation:

The third ray is the blue ray in the following figure

Therefore, the third ray is a ray parallel to the axis that refracts and passes through the focus of the right side.

So, the answer is:

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