What will be the position and nature of the image of an object positioned between C and F of a concave mirror? 

The correct answer is Beyond C, real and inverted.

Key Points

• When an object is placed between the center of curvature (C) and the focal point (F) of a concave mirror, the image formed is real, inverted, and located beyond C.
• The image is formed by the reflection of light rays that converge after bouncing off the mirror surface.
• The image size is larger than the object, making it magnified.
• This type of image formation is utilized in various optical devices like telescopes and microscopes.
• Concave mirrors are often used in applications where magnified images of objects are required.

Additional Information

• Concave Mirrors:
  • Concave mirrors have a reflective surface that curves inward, resembling a portion of the interior of a sphere.
  • They are also known as converging mirrors because they converge incoming light rays to a focal point.
• Center of Curvature (C):
  • It is the center of the sphere from which the concave mirror is a part.
  • The distance from the mirror to the center of curvature is called the radius of curvature.
• Focal Point (F):
  • The point where parallel light rays converge after reflecting off the concave mirror.
  • The distance from the mirror to the focal point is called the focal length.
• Image Formation by Concave Mirrors:
  • When an object is placed at different positions relative to the focal point and center of curvature, the nature of the image formed (real or virtual, upright or inverted) varies.
  • The mirror formula 1/f = 1/v + 1/u relates the object distance (u), image distance (v), and focal length (f).
• Applications:
  • Concave mirrors are used in various applications such as shaving mirrors, satellite dishes, headlights, and reflecting telescopes.
  • Their ability to form magnified images makes them useful in scientific and medical instruments.
