How Concave Mirrors Work

Types of Images Formed

Object Distance (S) Image Type Characteristics
Between F and Mirror Virtual Upright and magnified
At F No image Rays are parallel and do not converge
Beyond C (2F) Real Inverted and reduced
At C Real Inverted and same size

Basic Optics of Concave Mirrors

  • Concave mirrors focus light to a focal point, enabling various practical applications.
  • They can produce real or virtual images, depending on the object’s distance from the mirror.
  • The unique properties of concave mirrors enhance visibility and magnification, making them indispensable tools.
