. If its rear surface is silvered and object is placed at a distance 28 cm from the front face.

To find the final position of the image from the silvered surface.

Solution:

When an object is placed infront of the glass slab it shift the object in the direction of incident light and form an image at a distance x

x=t[1−

Distance of object from virtual mirror,

=(28+6)−x=34−x=34−2=32cm

Virtual mirror will form the image of object at a distance 32 cm behind the actual mirror.

As the virtual mirror is 2 cm from the real mirror.

Therefore the distance of image from actual plane mirror

i.e., 32-2=30 cm infront of the mirror.

Therefore the object is 30 cm behind the
