The image formed by a concave mirror is virtual, erect and magnified. The position of object is : (a) at focus (b) between focus and centre of curvature (c) at pole (d) between pole and focus
The image formed by a concave mirror is real, inverted and of the same size as the object. The position of the object must then be : (a) at the focus (b) between the centre of curvature and focus (c) at the centre of curvature (d) beyond the centre of curvature
The image formed by a concave mirror is observed to be virtual, erect and larger than the object. Where should be the position of the object?
(a) Between the principal focus and the centre of curvature
(b) At the centre of curvature
(c) Beyond the centre of curvature
(d) Between the pole of the mirror and its principal focus.
Question 30 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
