Virtual Object

Assertion : Focal length of a convex mirror is 20 cm. If a real object is placed at distance 20 cm from the mirror, its virtual erect and diminished image will be formed. Reason : If a virtual object is placed at 20 cm distance, its image is formed at infintiy.

Which of the following always forms virtual image for real objects ?

A convex mirror always produces a virtual image of real object independent of the location of the object use mirror equation to peove it.

A concave mirror of focal length 0.15 m forms an in image doubled of the linear dimension of the object. If the image is virtual then the object distance—
