Properties of Images at the Curvature
- When an object is positioned at the center of curvature (C) of a concave mirror:
- The image formed is real, inverted, and of the same size as the object.
- The image is located at the same distance from the mirror as the object.
- Optical characteristics:
- The distance from the mirror to the image (v) equals the distance from the mirror to the object (u).
- The magnification (M) is equal to -1, indicating size parity.
Properties of Images Behind the Curvature
- When an object is placed between the center of curvature (C) and the focus (F):
- The image is real, inverted, and larger than the object.
- The image appears beyond the center of curvature.
- Optical characteristics:
- The distance from the mirror to the image is greater than the distance from the mirror to the object.
- The magnification (M) is greater than 1, indicating the image is larger.
Summary of Key Differences
- Position:
- At C: Image is at C.
- Behind C: Image is beyond C.
- Nature:
- At C: Real and inverted, same size.
- Behind C: Real and inverted, larger size.
- Magnification:
- At C: M = -1.
- Behind C: M > 1.
Understanding these properties of mirrors is crucial for applications in optics, photography, and various fields of engineering.
