What will be the difference in the size of the image of the same object formed by a small and a large plane mirror ?

Academic Physics NCERT Class 7

A plane mirror would form an image of the exact same size as the size of the object. It doesn't change with the change in the size of the mirror (if it is a plane mirror)

Image formed by a plane mirror is:$(a)$. virtual, behind the mirror and enlarged.$(b)$. virtual, behind the mirror and of the same size as the object.$(c)$. real at the surface of the mirror and enlarged.$(d)$. real, behind the mirror and of the same size as the object.
State the characteristics of the image formed by a plane mirror.
Explain the characteristics of Image formed by a Plane Mirror"."
State any four characteristics of the image of the objects formed by a plane mirror.
What are the characteristics of an image formed on a plane mirror?
Whatever be the position of the object, the image formed by a mirror is virtual, erect and smaller than the object. The mirror then must be:(a) plane (b) concave (c) convex (d) either concave or convex
If an object is placed at a distance of 0.5 m in front of a plane mirror, the distance between the object and the image formed by the mirror will be$(a)$. 2 m$(b)$. 1 m$(c)$. 0.5 m$(d)$. 0.25 m
What kind of mirror is required for obtaining a virtual image of the same size as the object?
State where an object must be placed so that the image formed by a concave mirror is:(a) erect and virtual.(b) at infinity.(c) the same size as the object.
Can an image formed by a plane mirror be obtained on screen?
The image of an object formed by a plane mirror is:(a) virtual (b) real (c) diminished (d) upside-down
The image seen in a plane mirror cannot be formed on a screen. What name is given to this type of image?
Fill in the blanks:$(a)$. An image that cannot be obtained on a screen is called ____________.$(b)$. Image formed by a convex __________ is always virtual and smaller in size.$(c)$. An image formed by a __________ mirror is always of the same size as that of the object.$(d)$. An image that can be obtained on a screen is called a _________ image.$(e)$. An image formed by a concave ___________ cannot be obtained on a screen.
If the image formed by a convex lens is of the same size as that of the object, what is the position of the image with respect to the lens?
Boojho and Paheli were given one mirror each by their teacher. Boojho found his image to be erect and of the same size whereas Paheli found her image erect and smaller in size. This means that the mirrors of Boojho and Paheli are, respectively$(a)$. plane mirror and concave mirror.$(b)$. concave mirror and convex mirror.$(c)$. plane mirror and convex mirror.$(d)$. convex mirror and plane mirror.
