00:01 Hello and welcome to this video solution of numerates.

00:03 So here you have to describe an activity to show that the incident ray the reflected ray and the normal at the point of incidence all lie in the same plane so what you do is you take a piece of paper and spread it across a table fine so let's say from the top view i'm showing it place it over the table right you take a plane meter and put it vertically of the table like this right displaced vertically it is projecting out of the upwards to the table right okay and you do one thing you just keep a portion of this spreaded sheet which is hanging out of the table like this let's say now you take a torch okay place it somewhere around here and project a light onto the mirror so the light will move something like this right somewhere around here and you note down the right you draw the straight line along which the light is moving the way you have placed the the torch right so let's see if it plays the torch at an angle like this so you measure you draw a straight line on that paper as it you will see that it's some projecting somewhere around the plane mirror right at this point let's say now you move from the other to the other side to see the reflected light so here you have the eyes okay let's say and you see that the reflected lies is coming like this right so again from here you draw it on a straight line you will see that both actually converge to this point which is the point of incidence right so this this oh which is the point of incidence right and if you draw a line which is perpendicular to that then this will be the normal right so if you see here these three things the ray the incident ray the reflected ray and the normal all three things all three lines actually meet at one point which is this point right at the mirror center here now now this doesn't prove that they are lie on the same plane right, so what you need to do is you need to move your eyes a bit downwards from here let's say that this this portion of the sheet is hanging below the table so you try to watch your with your eyes a bit below the horizontal surface of this table right then you cannot see anything right that means everything is lying on the same plane, right, of the sheet of paper.
