Question
An object is standing towards the left of a concave lens. What should be the sign of the object distance?
- Positive
- Negative
- Neutral
- Cannot say
Hint:
Object is placed to the left of the mirror/lens.Now think about cartesian system for sign
The correct answer is: Negative
- According to Cartesian sign convention, object distances (u) are always negative as the object is placed to the left of the mirror/lens.
