Plane Mirror Image

A virtual, upright, same-sized image formed by a flat reflecting surface.

Concave Mirror Image Size

The size of the image formed by a concave mirror changes depending on the object's position relative to the mirror's focal point.

Convex Mirror Image

Always produces a virtual, upright, and diminished image.

Real Image

An image formed when light rays actually converge at a point.

Study Notes

Questions for Properties of Images Formed by Mirrors

  • What are the key characteristics of images formed by plane mirrors?
  • How do the sizes and orientations of images formed by concave mirrors vary with the object's position?
  • What is the relationship between the object distance, image distance, and focal length for convex mirrors?
  • How does the nature of the image formed by a mirror depend on the type of mirror and the object's location?
  • What are the conditions for real and virtual images in spherical mirrors?
  • How do the magnification and nature of the image formed by a mirror change with the position of the object?
  • How can the properties of images be determined using ray diagrams?
  • What are the similarities and differences in image formation for plane, concave, and convex mirrors?

Image Formation

  • Light rays originating from a point source on an object reflect off a mirror and converge (or appear to converge) at a point to form an image.
  • The position, size, and nature of the image depend on the type of mirror and the object's position.
  • Ray diagrams are used to trace the path of reflected rays and locate the image.

Types of Mirrors

  • Plane mirrors: Flat reflecting surfaces that produce virtual, upright, and same-sized images regardless of the object's position.
  • Concave mirrors: Spherical mirrors with a reflecting surface that curves inward. They can form both real and virtual images, depending on the object's position relative to the focal point.
  • Convex mirrors: Spherical mirrors with a reflecting surface that curves outward. Convex mirrors always produce virtual, upright, and diminished images.

Applications of Mirrors

  • Plane mirrors: Used in household items like dressing tables, mirrors, and security systems, and for observing objects on different perspectives.
  • Concave mirrors: Used in telescopes, searchlights, and as shaving mirrors, allowing for magnification or focusing light, based on the specific application.
  • Convex mirrors: Used as rearview mirrors in cars and other vehicles, expanding the field of view, and reducing blind spots and increasing safety.

Real vs. Virtual Images

  • Real images: Images formed when light rays actually converge at a point. They can be projected onto a screen.
  • Virtual images: Images formed when light rays appear to diverge from a point. They cannot be projected onto a screen.

Image Characteristics

  • Size: The height of the image compared to the height of the object.
  • Orientation: Whether the image is upright or inverted.
  • Nature: Whether the image is real or virtual.
  • Position: The distance of the image from the mirror.
  • Magnification: The ratio of the height of the image to the height of the object.
