    About the Lecture

    The lecture Mirrors and Lenses by Jared Rovny is from the course Geometrical Optics.


    Included Quiz Questions

    1. A ray of light incoming to a circular mirror parallel to the mirror axis
    2. A ray of light incoming to a circular mirror perpendicular to the mirror axis
    3. Two perpendicular rays of light passing through the center C
    4. Two parallel rays of light passing through the center C
    5. A ray of light passing through the mirror axis at twice the mirror radius
    1. Any light at a slight angle will diverge more and more over longer distances, missing the mirror
    2. Any light that is not parallel will destructively interfere over long distances
    3. A non-parallel ray will destructively interfere with other non-parallel rays upon arrival at the mirror
    4. Parallel rays always constructively interfere, such that at long distances they dominate the amount of light
    5. Mirrors act as focusers of light, causing the beams to become parallel over long distances
    1. A source emits light in all directions, which is the same behavior as an effective “source” where beams intersect
    2. Whenever two beams intersect, they form an image at the point of intersection
    3. When two beams intersect, the focal point and the center of a mirror coincide for the image to come into focus for an observer
    4. The point of intersection occurs at the focal point of a mirror, causing an image to form
    5. The point of intersection of two beams is always equidistant from the observer as the original source
    1. Parallel rays go through the focus; rays through the focus reflect parallel
    2. Parallel rays go through the center; rays through the focus reflect parallel
    3. Parallel rays go through the focus; rays through the center reflect parallel
    4. Parallel rays go through the center; rays through the center reflect parallel
    5. None of these is accurate
