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

Q. If a concave mirror forms a real magnified image of an object, the object is located

(a) between pole and focus
(b) between focus and centre of curvature
(c) beyond centre of curvature
(d) at centre of curvature

Q. A concave mirror produces magnification of +4. The object is placed:

(a) at the focus
(b) between focus and centre of curvature
(c) between focus and pole
(d) beyond the centre of curvature

Q. Which of the following ray diagrams correctly represents the image formation of an object placed between the centre of curvature and the focus of a concave mirror?

Q. Draw a ray diagram for concave mirror when object is placed between focus and centre of curvature. Also write position, nature and size of image.

Q.

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.
