Question

If the ratio of focal length and image distance for concave mirror is positive then

• A. Image is formed in front of the mirror and is inverted
• B. Image is erect
• C. Image is virtual
• D. None of these

Answer 1

The correct option is A Image is formed in front of the mirror and is inverted

we know that the focal length of a concave mirror is negative as its focus lies on the left hand side of the mirror so if f/v is positive then it means v is also negative.
If v is negative then it means image distance is also negative so the image is formed on the same side of the mirror. Such images are always real and inverted.
