Question

We know that a plane mirror forms only a single image of an
object placed in front of it. We will now describe what happens
when an object is placed between two plane mirrors which are
inclined at an angle to each other. When two plane mirrors are
kept inclined at an angle, they can form multiple images of an
object. This is because the image of object formed in one plane
mirror acts as object for the other plane mirror. It has been found
that if two plane mirrors are inclined at an angle x, then the
number of images formed in them is given by the formula:
360°
No. of images formed - 1
By using this formula, we can calculate the number of images
formed (or seen) when two plane mirrors are inclined at angles
of 180°, 120°, 90°, 60°, 45° and 0°, respectively.
How can we get multiple images of an object?
Why this multiple images are formed?​

Answer 1

Answer:

Besides the fact that plane mirror images are virtual, there are several other characteristics that are worth noting. The second characteristic has to do with the orientation of the image. If you view an image of yourself in a plane mirror (perhaps a bathroom mirror), you will quickly notice that there is an apparent left-right reversal of the image. That is, if you raise your left hand, you will notice that the image raises what would seem to be it's right hand. If you raise your right hand, the image raises what would seem to be its left hand. This is often termed left-right reversal. This characteristic becomes even more obvious if you wear a shirt with lettering. For example, a shirt displaying the word "NIKE" will read "EKIN" when viewed in the mirror; a shirt displaying the word "ILLINOIS" will read "SIONILLI;" and a shirt displaying the word "BOB" will read "BOB." (NOTE: Not only will the order of letters appear reversed, the actual orientation of the letters themselves will appear reversed as well. Of course, this is a little difficult to do when typing from a keyboard.) While there is an apparent left-right reversal of the orientation of the image, there is no top-bottom vertical reversal
