Answer:


Explanation:


When an object is placed in front of a mirror, an image is formed as a result of the reflection of light rays. The type of mirror used determines the characteristics of the image formed. In this case, a man with a height of 6 meters is observing an image of 2 meters height erected, so we need to determine the type of mirror required to produce such an image.


Type of Mirror


There are three types of mirrors - concave, convex, and plane. Let us see the properties of each mirror type before we decide which mirror is used in this case.



  • Concave Mirror: A concave mirror is also known as a converging mirror. It is a mirror with a reflecting surface that is curved inwards. When an object is placed in front of a concave mirror, the reflected rays converge at a focal point. The image formed by a concave mirror can be real or virtual, depending on the position of the object.

  • Convex Mirror: A convex mirror is also known as a diverging mirror. It is a mirror with a reflecting surface that is curved outwards. When an object is placed in front of a convex mirror, the reflected rays diverge. The image formed by a convex mirror is always virtual, smaller, and upright.

  • Plane Mirror: A plane mirror is a flat mirror with a reflective surface. When an object is placed in front of a plane mirror, the reflected rays are parallel to the incident rays. The image formed by a plane mirror is always virtual, upright, and of the same size as the object.



Conclusion


From the given information, we can conclude that a plane mirror is used in this case. This is because the image formed by a plane mirror is always of the same size as the object. Therefore, the man with a height of 6 meters observing an image of 2 meters height erected can only be possible with a plane mirror.


Answer: The mirror used is a plane mirror.
