  • How can you identify a concave mirror based on the behavior of light rays coming from the left?
    A concave mirror converges parallel incoming light rays toward a focal point after reflection, causing the rays to come together.
  • How is an image formed by a plane (flat) mirror?
    An image is formed by a plane mirror when light rays reflect off the mirror at equal angles, creating a virtual image that appears upright, the same size as the object, and located the same distance behind the mirror as the object is in front.
  • How can you identify a convex mirror based on a ray diagram?
    A convex mirror causes parallel incoming light rays to diverge after reflection, making the rays spread apart and never converge; the reflected rays appear to originate from a point behind the mirror (the apparent focus).
  • What kind of images does a diverging (convex) mirror produce?
    A diverging (convex) mirror produces virtual, upright, and reduced images because the reflected rays never actually converge.
  • How do convex and concave mirrors compare in terms of how they affect light rays and the images they produce?
    Concave mirrors converge light rays and can produce real or virtual images depending on object position, while convex mirrors diverge light rays and always produce virtual, upright, and reduced images.
  • What does a ray diagram illustrating the law of reflection show?
    A ray diagram illustrating the law of reflection shows that the angle of incidence equals the angle of reflection for light rays striking a mirror surface.
  • What best describes the image produced by a flat (plane) mirror?
    A flat (plane) mirror produces a virtual, upright image that is the same size as the object and appears the same distance behind the mirror as the object is in front.
  • Which features differentiate ray diagrams of reflected and refracted light?
    Ray diagrams of reflected light show rays bouncing off surfaces at equal incident and reflected angles, while refracted light diagrams (not covered in the provided materials) would show rays bending as they pass through different media. For mirrors, key features include the direction of reflected rays, the type of mirror (concave, convex, plane), and the location of the image (real or virtual).
  • What is the significance of the central axis in determining the orientation of an image in a ray diagram for mirrors?
    The central axis helps determine if the image is upright or inverted by showing whether the convergence of light occurs above or below it. If the convergence is below the axis, the image is inverted; if above, it is upright.
  • Why does a concave mirror not form an image when the object is placed at the focal point?
    When the object is at the focal point, the reflected rays are parallel and never converge, so no image is formed. This is because the incident and reflected angles are equal, resulting in rays that do not intersect.
