  • What is the focus in a concave mirror ray diagram?
    The focus is the point where collimated (parallel) light converges after reflecting off the mirror; its distance from the mirror's apex is called the focal length.
  • How does a ray parallel to the central axis reflect in a concave mirror?
    A ray parallel to the central axis reflects through the focus of the concave mirror.
  • What happens to a ray that passes through the focus before hitting a concave mirror?
    A ray passing through the focus reflects off the mirror parallel to the central axis.
  • How does a ray directed at the apex of a mirror reflect?
    It reflects at the same incident angle, following the law of reflection.
  • How is the image formed by a concave mirror when the object is beyond the focal point?
    The image is real and inverted, formed where the reflected rays converge below the central axis.
  • What happens when an object is placed at the focal point of a concave mirror?
    No image is formed because the reflected rays are parallel and never converge.
  • What is the apparent focus in a convex mirror?
    The apparent focus is a point where reflected rays seem to converge, but in reality, the rays diverge and never actually meet.
  • How does a ray parallel to the central axis reflect in a convex mirror?
    It reflects away from the focus, diverging from the mirror.
  • What happens to a ray directed towards the focus in a convex mirror?
    It reflects off the mirror parallel to the central axis.
  • What type of image does a convex mirror always produce?
    A convex mirror always produces a virtual, upright image.
  • What is the focal length of a plane mirror?
    The focal length of a plane mirror is considered to be infinity, as it neither converges nor diverges light.
  • How does a ray parallel to the central axis reflect in a plane mirror?
    It reflects off the mirror parallel to the central axis.
  • Where does the image appear in a plane mirror relative to the object?
    The image appears the same distance behind the mirror as the object is in front of it.
  • What type of image does a plane mirror produce?
    A plane mirror always produces a virtual, upright image of the same height as the object.
  • Which type of mirror can produce real images?
    Only concave mirrors can produce real images, as they converge light; convex and plane mirrors cannot.
