The correct answer is option 'A', highly enlarged.
Explanation:
When an object is placed at the focus of a concave mirror, the image formed is highly enlarged. This is because a concave mirror is a converging mirror, meaning it brings parallel rays of light to a focal point after reflection.
When an object is placed at the focus of a concave mirror, the rays of light that are reflected from the mirror become parallel to each other. These parallel rays then appear to come from the focal point on the same side of the mirror as the object.
- Properties of Concave Mirrors:
1. Focal Point: The focal point is the point on the principal axis where parallel rays of light converge or appear to diverge from after reflection. For a concave mirror, the focal point is located in front of the mirror.
2. Principal Axis: The principal axis is an imaginary line that passes through the center of curvature (C) and the vertex (V) of the mirror.
3. Center of Curvature: The center of curvature is the center of the sphere from which the mirror is derived. It is located on the principal axis, and for a concave mirror, it is located in front of the mirror.
4. Vertex: The vertex is the midpoint of the mirror, located on the principal axis.
- Image Formation:
When an object is placed at the focus of a concave mirror, the rays of light that are reflected from the mirror become parallel to each other. These parallel rays then appear to come from the focal point on the same side of the mirror as the object.
1. The image formed by a concave mirror when the object is placed at the focus is highly enlarged.
2. The image is virtual, meaning that it cannot be projected onto a screen.
3. The image is erect, meaning it is positioned in the same orientation as the object.
4. The image is located behind the mirror, on the same side as the object.
5. The image distance is equal to the focal length of the mirror.
- Conclusion:
When an object is placed at the focus of a concave mirror, the image formed is highly enlarged. This is because the parallel rays of light reflected from the mirror appear to come from the focal point, resulting in an image that is larger than the object.
