Object is always kept on the left side of the mirror therefore its distance is always negative when taken from left of pole.

Understanding the New Cartesian Sign Conventions
The new Cartesian sign conventions are essential in optics, especially when dealing with lenses and mirrors. Here's a detailed explanation of why option 'A' is correct.
1. Object Distance
- The object distance (denoted as 'u') is considered negative when measured from the pole of the mirror or lens towards the object, which is typically on the left side in conventional diagrams.
- This means that if an object is placed on the left side of the mirror or lens, the distance from the pole to the object is negative.
2. Image Distance
- The image distance (denoted as 'v') is positive when the image is formed on the right side of the mirror or lens.
- If the image is formed on the left side (same side as the object), it is considered negative.
3. Principal Focus
- Distances are measured from the principal focus only in specific contexts, particularly when analyzing focal lengths.
- However, this statement is too broad and does not represent a key convention as per the standard sign rules.
4. Image Position
- While images can form above or below the principal axis, this is not universally applicable.
- Images can also form below the principal axis, especially in concave mirrors or converging lenses.
Conclusion
In summary, the correct answer is option 'A' because it accurately reflects the convention that the object distance is negative when taken from the left of the pole. This approach helps maintain consistency in calculations and analyses in optics. Understanding these conventions is crucial for solving problems related to lenses and mirrors effectively.
