Question
An image is formed at the opposite side of the lens as the object. The sign on the image distance will be ____ the object distance.
- Same as that of
- Opposite to that of
- Always positive
- Always negative
Hint:
- Distances that are calculated in the orientation of the incident ray are positive and the distances calculated in the direction opposite to the incident rays are negative.
The correct answer is: Opposite to that of
- According to the spherical lens, the sign convention is as follows:
- Distances that are calculated in the orientation of the incident ray are positive and the distances calculated in the direction opposite to the incident rays are negative.
- So object distance is negative and image distance is positive
- The sign on the image distance will be __Negative__ the object distance.
