In the experiment, the angles between the laser and the optical bench, θbench, and between the laser and the normal to the mirror, θmirror, are measured. What is the relationship between θbench and the customary angles?

A. θbench=r
B. θbench=r–i
C. θbench=i–r
D. θbench=i+r
E. None of the above

I know that it's not B or D. Any help is appreciated!

That link split up by spaces is the figure (if you take the spaces out) that goes with the experiment.

To determine the relationship between θbench and the customary angles, we need to understand the given information more clearly. However, the provided information does not explicitly mention what the "customary angles" refer to in this context. Without additional context or information, it is difficult to determine the exact relationship between θbench and the customary angles.

To find the correct answer, it is recommended to review the relevant materials, such as the experiment setup, any given diagram, or accompanying text, to identify how the customary angles are defined or referenced. Paying attention to any relevant equations or principles related to the experiment could provide additional clues.

If the given information is incomplete or unclear, you may consider seeking clarification from the instructor, referring to textbooks or lecture notes, or discussing with classmates who may have a better understanding of the subject matter.
