2. A mirror which can produce a magnification
of +1 is
(1 Point)
O convex mirror
concave mirror
plane mirror
both concave mirror and plane
mirror​

Answer 1

Answer:

Concave mirror can produce image of magnification -1 and convex mirror always made diminished image so its magnification is always less than 1 and plane mirror always produce image of same size so it will produce image if magnification of 1.

Answer 2

Answer :

A mirror which can produce a magnification of +1 is a plane mirror .

$\underline{\bf{Explanation\::}}}$

The positive sign means image formed by a plane mirror is virtual & erect. The size of image is equal to the size of object.

Formula of magnification :

$\sf{m=\dfrac{Height\:of\:Image\:(I)}{Height\:of\:object\:(O)} =\dfrac{Distance\:of\:Image}{Distance\:of\:object} =\dfrac{v}{u} }$
