Concave Mirror Image Formation: Object at Infinity
When an object is placed at infinity in front of a concave mirror, light rays coming from the object are nearly parallel.
These parallel rays converge at the focal point (F) after reflection from the concave mirror.
- Image Location: The image is formed at the focal point (F) of the mirror.
- Image Characteristics:
- Size: The image is highly diminished (point-sized).
- Nature: The image is real, as the rays actually converge at the focal point.
- Orientation: The image is inverted.
Therefore, the image formed by a concave mirror when the object is at infinity is highly diminished, real, and inverted.
