A particle is dropped along the axis from a height `(f)/(2)` on a concave mirror of focal length f as shown in figure. Find the maximum speed of image .

An object is placed in front of a concave mirror of focal length f as shown in figure. Choose the correct shape of the image.

An object is placed between a plane mirror and a concave mirror of focal length 15 cm as shown in Figure . Find the position of the images after two reflections.

A rod AB of length 5 cm is placed in front of a concave mirror of focal length 10 cm as shown in figure. The length of the image of AB formed by the mirror is

For a concave mirror of focal length f, image is 2 times larger. Then the object distance from the mirror can be

(a) A short linear object of length b lies along the axis of a concave mirror of focal length f at a distance u from the pole. What is the size of the image? (b) If the object begins to move with speed V_(0) , what will be the speed of its image?

A particle is moving at a constant speed V from a large distance towards a concave mirror of radius R along its principal axis. Find the speed of the image formed by the mirror as a function of the distance x of the particle from the mirror.

A short linear object, of length l, lies along the axis of a concave mirror, of focal length f, at a distance d from the pole of the mirror. The size of the image is then (nearly)

A short linear object of length b lies along the axis of a concave mirror of focal length f at a distanee u from the pole of the mirror. The size of the image is approximately equal to
