The image of an object formed in a plane mirror is

Answer 1

$\huge\boxed{\underline{\mathcal{\red{A}\green{N}\pink{S}\orange{W}\blue{E}\pink{R}}}}$

$\dashrightarrow$The image formed by a plane mirror is always virtual (meaning that the light rays do not actually come from the image), upright, and of the same shape and size as the object it is reflecting. A virtual image is a copy of an object formed at the location from which the light rays appear to come.

$\dashrightarrow$They are used in periscopes, for signalling, in kaleidoscopes, to see round dangerous bends, in meters, as mirror tiles, in a sextant, in an overhead projector, an SLR camera, car wing mirrors, in microscopes and as reflecting number plates to mention only some!

Answer 2

$\huge\underline \mathfrak {answer}$

The image which is formed by a plane mirror is always erect and same size of the object and of same distance as that of the object. The images formed by the plane mirror is vitual, and it can't be taken on screen. There is no lateral inversion of image on plane mirror. In other words there is no interchange of the side of the image in plane mirror. But the image which is formed is literally inverted. The location of the image is given by the fact that, the image is situated at the same perpendicular distance behind the mirror as the object is in front of it.

• For two mirrors kept perpendicular to each other three images are formed for an object kept in between
• For two mirrors kept. parallel to each other, an infinite number of images are formed for an object kept between them

• The most common and wide use is as looking glass
• In barbers shop for seeing the hair cut at the back of the head
