An object is placed at the centre of curvature of a concave mirror. The focal length of the mirror is 20cm. A plane mirror is placed on the left of the object as shown in the figure. Considering the image formed by the plane mirror as the object for the concave mirror, where will the new image be formed?

Q. An object is placed between a convex and a concave mirror. The pole of the convex mirror coincides with the centre of curvature of the concave mirror. Suppose an object is placed at the focus of the concave mirror. What will be the nature of the image formed by the concave mirror of the image formed by the convex mirror?

Q. A point object is kept between a plane mirror and a concave mirror facing each other. The distance between the mirrors is $22.5cm$. Plane mirror is placed perpendicular to principal axis of concave mirror. The radius of curvature of the concave mirror is $20cm$. What should be the distance of the object from the concave mirror so that after two successive reflections the final image is formed on the object itself? (Consider first reflection from concave mirror)

Q. An object is placed at the centre of curvature C of a concave mirror, the image will be formed at

Q. An object $\left(ABED\right)$ is placed in front of a concave mirror beyond the centre of curvature $\left(C\right)$ as shown in the figure. The shape of image will be :
(Consider $DE$ and $AB$ as extended objects)

Q. An object is placed beyond the centre of curvature (C) of a concave mirror. What will be the characteristics of the image formed?
