What is the velocity (in cm`s^(-1)` ) of image in situation shown in figure, `(O=` object, `f=` focal length ). Object moves with velocity `10cm//s` and mirror moves with velocityy `2cms^(-1)` as shown.

Find the velocity of image of a moving particle O in the situation as shown in the figure.

Find the velocity of the image of a moving object in situation shown in figure in which object and mirror velocities in horizontal and vertical directions are shown.

Focal length of the mirror shown in figure is 20cm. Find the image position and its velocity.

Focal length of the mirror shown in figure is 20cm. Find the image position and its velocity.

(a) In the figure shown a slab of refractive index (3)/(2) is moved toward a stationary observer with speed 6 cm//s . A point O is observed by the observer with the help of paraxial rays through the slab. Both O and observer lie in are. Find the velocity (in cm//s ) with which the image will appear to move to observer. (b) in the previous question if the object moves towards rigth with a velocity of 6 cm//s and find the velocity of the final image (in cm//s ) as seen by observer :

A point object is placed on the principle axis at 60cm in fornt of a concave mirror of focal length 40cm on the principle axis. If the object is moved with a velocity of 10cm/s (a) find velocity of image along principle axis (b) perpendicular axis, find the velocity of image at the moment.

An object and a plane mirror are shown in figure. Mirror is moved with velocity V as shown. The velocity of image is : .
