A concave mirror of focal length `20 cm` is cut into two parts from the middle and the two parts are moved perpendicularly by a distance `1 cm` from the previous principal axis `AB` .find the distance between the images formed by the two parts?

A concave mirror of focal length 20cm is cut into two parts from the middle and the two parts are moved perpendicularly bya distanc e 1cm from the previous principal axis AB .find the distance between the images fromed by the two parts?

A concave mirror forms real image of a point source lying on the optical axis at a distance of 50cm from the mirror. The focal length of the mirror is 25cm. The mirror is cut in two, and its halves are drawn at a distance of 1 cm apart in a direction perpendicular to the optical axis. Q. The distance between the two images formed by the two halves of the mirror is

An object is placed between two identical convex mirrors X and Y of focal length 15 cm a the midpoint on their common principal axis. If the two mirrors are separated by a distance of 20 cm, determine the distance of the first two images formed in the mirror Y .

An object is placed at a distance of 20 cm from the pole of a concave mirror of focal length 10 cm. The distance of the image formed is

A symmetrical converging convex lens of focal length 10 cm & diverging concave symmetrical lens of focal length -20 cm are cut from the middle and perpendicularly and symmetrically to their principal axis. The parts thus obtained are arrenged as shown in the figure. Find the focal length (in cm ) of this arragement

An object is located at a distance 30cm on principal axis from the pole of a concave mirror of focal length 20cm. Suddenly the mirror is displaced by a distance 1.5 cm in the direction normal to its principal axis. Calculate the displacement of image produced by the mirror due to this.

Concave mirror forms the real image of a point source lying on the optical axis at a distance of 50 cm from the mirror. The focal length of the mirror is 25 cm. The mirror is cut into and its halves are drawn a distance of 1 cm apart in a direction perpendicular to the optical axis. How will the image formed by the halves of the mirror be arranged?

A point object is placed at a distance 20 cm from the focus of a concave mirror of radius of curvature 20 cm. Find the distance (in cm) of the image from the focus.
