CONCEPT:
Mirror:
- The optical instrument which reflects the light and makes the image of the object is called a mirror.
- The mirror has a spherically curved reflecting surface is called a spherical mirror.
There are two types of spherical mirror:
- Concave mirror: The spherical mirror having an inward reflecting surface is called a concave mirror.
- The images form by the concave mirror can be real as well as virtual.
- Convex mirror: The mirror whose reflecting surface is outward is called a convex mirror.
- The images formed by the convex mirror are always virtual.
EXPLANATION:
- The images formed by the convex mirror for different positions of the object is given as,
S. No | Position Of Object | Position of Image | Size of Image | Nature of Image |
1 | At Infinity | At the focus F, behind the mirror | Highly diminished | Virtual and Erect |
2 | Between Infinity and the Pole | Between P and F, behind the mirror | Diminished | Virtual and Erect |
- When the object is placed at infinity the image is formed as,
- When the object is placed between infinity and the pole the image is formed as,
- From the above table and diagram, it is clear that for the convex mirror as the object is moved closer to the convex mirror, the height of the image increases. Hence, option 2 is correct.
