A plane mirror is placed $24.5$ cm in front of a concave mirror of focal length $10$ cm. Find where an object can be placed between two mirrors so that the first image of both mirrors coincides.

Q. A plane mirror is placed $22.5cm$ in front of a concave mirror of focal length $10cm$. An object can be placed between the two mirrors so that the first image in both the mirror coincides. The object distance from the spherical mirror is

Q. A plane mirror is placed at a distance of $50\text{cm}$ from a concave mirror of focal length $16\text{cm}$. Where should a short object be placed between the mirrors and facing both the mirrors so that its virtual image in the plane mirror coincides with the real image in concave mirror?

Q. If an object is placed 10 cm in front of a concave mirror of focal length 20 cm, the image will be:

Q. A point object is placed in the middle of two concave mirrors. The focal length of each mirror is 10 cm to obtain single image of point object, the distance between two mirrors in cm will be

Q. A concave and a convex mirror of focal lengths $10\text{cm}$ each are placed at a distance $d\text{cm}$ apart. An object $\text{AB}$ is placed in between the mirrors at a distance of $10\text{cm}$ from the convex mirror. If first ray is incident on the convex mirror and then on the concave mirror then find the distance $d$ between both the mirrors, so that final image will be formed at the object's position.
