A student of height 1.9 m can see his full image in a plane mirror fixed on a wall his eyes are 18.5 m from the floor level what is the minimum level of a plane mirror required to get full image of the student
To determine the minimum level of a plane mirror required to get a full image of the student, we need to consider the concept of the height of the image formed by a plane mirror.
In the case of a plane mirror, the height of the image formed is equal to the height of the object. So, the student's height of 1.9 m will also be the height of the image.
Now, the student's eyes are 18.5 m from the floor level. In a plane mirror, the image is formed at the same distance behind the mirror as the object is in front of it. Therefore, the image of the student will also be formed 18.5 m from the floor level.
To get the full image of the student, the mirror needs to be positioned such that the top of the mirror is at the height of the student's eyes (also the height of the image). So, the minimum level of the plane mirror required would be 18.5 m from the floor level.
In summary, to obtain a full image of the student, the level of the plane mirror needs to be set at a height of 18.5 m from the floor level.
How can "A student of height 1.9 m" have his eyes 18.5m from the floor level?
And what do you mean by " minimum level of a plane mirror"? How high the bottom is above the floor?
