Question
Compare the characteristics of an image formed by a convex mirror and a concave mirror, when object is beyond center of curvature, but not at infinity.
Solution
Characteristics of the image formed by concave mirror when object is beyond the centre of curvature, but not at infinity are:
- Image formed is real.
- Image formed is inverted.
- Image formed is diminished.
- Image is formed between the centre of curvature (C) and principal focus (F), in front of the concave mirror.
Characteristics of the image formed by convex mirror when object is beyond centre of curvature, but not at infinity are :
- Image formed is virutal.
- Image formed is erect.
- Image formed is diminished.
- Image is always formed between pole and principal focus and behind the convex mirror.
