Answers
Answer:
the image formed by a concave mirror can be smaller than the object, bigger than the object, inverted and erect too.
but the answer can be said as option 4 or 1.
Explanation:
when the object is at infinity, at far distance and beyond centre of curvature the image is inverted, small and real.
when the object is at centre of curvature, the image is real, inverted and same size.
when the object is between centre of curvature and focus and at focus, image is real, inverted and bigger.
when the object is between focus and pole, the image is virtual, erect and bigger. so in different cases the image is different in size. so it is the condition which decides about the image in concave mirror.
