Question

When an object is moved from the centre of curvature of a concave mirror towards its focus what change do you observe in the size of the image?

Answer 1

$\huge\bold{\mathtt{\purple{A{\pink{N{\green{S{\blue{W{\red{E{\orange{R}}}}}}}}}}}}}$$\huge \Rightarrow$

When the object is kept at the centre of curvature of a concave mirror, the size of the image is equal to the size of the object. As the object is moved towards the focus, the size of the image goes on increasing and finally when the object is kept at the focus, we get an infinitely magnified (enlarged) image.
