19. The image of a post in a plane mirror is 3 m high and 12 m behind the mirror. Find the size and position of the image if the object distance is halved.
Solution
as it is a plane mirror there will not be any magnification.
size of the object = size of the image = 3m
and distance of the object from the mirror is equal to the distance of the image......
when distance is halved , the size of the image is 3m and position is 6 m.
