A concave mirror produces a magnification of +4. The object is placed At the focus b) Between focus and centre of curvature Between focus and pole d) Beyond the centre of curvature

Mgnification of concave mirror when the object is placed at the centre of curvature

Draw ray diagrams showing the image formation by a concave mirror when an object is placed (a) between pole and focus of the mirror , (b) between focus and centre of curvature of the mirror (c ) at centre of curvature of the mirror , (d) a little beyond centre of curvature of the mirror (e) at infinity

An object is placed at the focus of a concave lens. Where will be image ?

When an object is placed between the focus and the pole of a concave mirror, the image formed is

The image formed by a concave mirror is seen to be virtual, erect and larger than the object. The position of the object must then be : (i) between the forus and curvature. (ii) at the centre of curvature. (iii) beyound the centre of curvature. (iv) between the pole of the morror and its forcus. Choos the correct altenative.
