Question

Which of the following sets of words are related to the concept of ray diagrams?

frequency, wavelength, period
center of curvature, focal point, principal axis
pitch, timbre, harmonics
longitudinal, transverse, circular

Answer 1

b, the second one. center of curvature, focal point, principle axis

Answer 2

Object Located at the Center of Curvature

The second ray passes through the focal point on the way to the mirror and reflects parallel to the principal axis. All concave and convex mirror ray diagrams can be constructed from knowledge of the behavior of these two rays. In the animation above, a right-side-up object is located above the principal axis
