1. Position of the image formed by a concave mirror when the object is placed at infinity - At F

Explanation:

➤ When the object is at infinity but the rays coming from it are parallel to principal axis.

Characteristics:

• Image is real.
• Image is inverted.
• Images diminished to a point.
• Imagine is formed at principal focus, in front of the concave mirror.

2. Position of the image formed by a convex mirror when the object is placed in front of it - Behind the mirror

Explanation:

➤ When the object is placed in front, the image formed by a convex mirror.

Characteristics:

• Image is virtual.
• Image is erect.
• Images diminished.
• Image is always formed behind the convex mirror.

3. Position of the image formed by a concave mirror when the object is placed between C and F - Beyond C

Explanation:

➤ When the object is in between of the centre of curvature and principal focus.

Characteristics:

• Image is real.
• Image is inverted.
• Image is enlarged
• Images formed beyond the centre of curvature in front of concave mirror.

4. Position of the image formed by a concave mirror when the object is placed at F - At infinity

Explanation:

➤ When the object is at principal focus of concave mirror.

Characteristics:

• Image is real.
• Image is inverted.
• Image is highly enlarged i.e, magnified.
• Image is formed at infinity, in front of the concave mirror.

5. Position of the image formed by a concave mirror when the object is placed at C - At C

Explanation:

➤ When the object is at centre of curvature of concave mirror.

Characteristics:

• Image is real.
• Image is inverted.
• Image is of the same size of object.
• Image is formed at the centre of curvature, in front of the concave mirror.
