Plane Mirror Formation of image

Plane Mirror Formation of image


Look at this picture. What do you find over here? If you place a candle in front of a
mirror, what will you see? You will see that an exact image of the
candle, you can see on the mirror. So how do you think this is happening? How
do you think that the candle that you’re placing in front of the mirror is
forming an image on the mirror? Let us find out. Look at the diagram that has been
represented on the board. Here the candle is represented by this circle. So what we are going to try and do now is
obtain an image for this candle on the mirror PQ. So to form an image, we’re going to need at least
two rays coming from the candle on to the mirror. So these rays have been depicted by these two arrows. These two rays are the incident rays
because they are coming from the candle and they’re hitting the mirror as
depicted by these arrow heads. So after these incident rays come and hit
the mirror, what will happen? They will bounce back. So after these rays bounce back, that is,
after they are reflected they reach the observer’s or in this case, the human eye. Now do you think that the human eye is able to trace this V path? It is not, the human eye cannot trace the V
path that the incident ray and the reflected ray is taking. So how does the human eye see the image? The human eye always perceives the image to be
coming from a straight line ,that is, the human eye perceives that the image is at
this point because like I mentioned, the human eye
cannot perceive this V path. It always perceives that the image is coming in a straight line path. So how are we
getting this image? Let us find out. We are obtaining the image on the mirror
by extrapolating these reflected rays. What is the meaning of extrapolating? We
are producing them backwards. So from this two points, we are producing the reflected ray
backwards and we find that these reflected rays
appear to be diverging from this point. Thus, we get the image of this object O,
that is, the candle at this point shown by I. As you can see, the image is formed
behind the object on the mirror. It is formed behind the object on the
mirror. So what did we learn? We learnt that when
you place any object in front of a mirror, you’re able to see its reflection.
How do you see its reflection? How can you find it out diagrammatically? By drawing a diagram of an object placed
in front of a mirror you need at least two rays. These two rays, after reflection
will appear to be diverging from a point that is behind the mirror. This is because the human eye cannot
perceive this V path. The human eye always perceive things in a straight line. Due
to this the image appears on the other side of the mirror.
