An extended object of size 2mm is placed on the principal axis of a converging lens of focal length 10cm. It is found that when the object is placed perpendicular to the principal axis the image formed is 4mm in size. The size of image when it is placed along the principal axis is "____________" mm.

A 2.5 dipote lens forms a virtual image which is 4 times the object placed perpendicually on the principle axis of the lens. Find the required distance of the object form the lens.

Point A (0, 1 cm) and B (12 cm, 5 cm) are the coordinates of object and image x-axis is the principal axis of the mirror. The, this object image pair is

Assertion : In case of a concave mirror if a point object is moving towards the mirror along its principal axis, then its image will move away from the mirror. Reason : In case of reflection (along the principal axis of mirror) object and image always travel in opposite directions.

A slab of glass of refractive index 1.5 and thickness 3cm is placed with the faces perpendicular to the principle axis of a concave mirror. If the radius of curvature of the mirror is 10cm , the distance at which an object must be placed from the mirror so that the image coincides with the object is

The image of an exend object placed perpendicular to the principal axis of a mirror, will be erect if
