Concave Mirror Image Formation: Object Between \(C\) and \(F\)
Understanding the image characteristics requires knowing how light rays behave with a concave mirror.
Scenario: An object is positioned between the mirror's centre of curvature (\(C\)) and its principal focus (\(F\)).
Ray Behavior Analysis
- A ray parallel to the principal axis reflects through the focus (\(F\)).
- A ray directed towards the centre of curvature (\(C\)) reflects back along the same path.
- For an object between \(C\) and \(F\), these reflected rays meet at a point beyond \(C\).
Image Characteristics
- Real: The image is formed by the actual convergence of reflected rays.
- Inverted: Real images formed by concave mirrors are always inverted with respect to the object.
- Enlarged: Since the rays converge beyond \(C\), the image size is magnified compared to the object.
Thus, the image formed is enlarged, real, and inverted.
