Question

Keep a mirror close to your face and look into it. Move the mirror backward and observe the image. What change do you observe? Try this activity using Convex, Concave mirrors. In which mirror do you get an inverted image ?At what distance does it happen?

Answer 1

1. When the mirror moves by a distance of minimum 25 cm. then only we can see our image in the plane mirror. 

2. If it is a concave mirror, as long as our face it with in the focus of the concave mirror a small virtual image of the face is seen. 

3. When the concave mirror is at a distance beyond its focus, then the image formed will be bigger in size. 

4. In the case of convex mirror a virtual, small image is formed in it when it is kept at a suitable distance form the face.
