Answer 1

Answer:

1. The mirror shown above is a plane mirror.

2. Characteristics of a plane mirror:

• The height of image formed is equal to that of height of object.
• The image formed is virtual & erect.
• The image is laterally inverted.
• The distance between the object and mirror is same to that of image and mirror.
• Image is formed inside the mirror.

3. The coating of silver in a transparent (glass, probably) surface is called coating of silver. It is used as it is the best reflector of light.

More:

• A plane kept in focus of a mirror normal to the principal axis is called focal plane.
• Focus of a plane mirror is not defined. (f = ∞ = ND.)
• Line joining the image to the object is 90° to the mirror surface. (See attachment.)
