The image formed by a plane mirror is always virtual (meaning that the light rays do not actually come from the image), upright, and of the same shape and size as the object it is reflecting. A virtual image is a copy of an object formed at the location from which the light rays appear to come. A mirror image (in a plane mirror) is a reflected duplication of an object that appears almost identical, but is reversed in the direction perpendicular to the mirror surface. As an optical effect it results from reflection off of substances such as a mirror or water.

No. The earth rotates from west to east on its axis. So, all the stars in the sky (except pole star) appear to move from east to west. With reference to earth, the pole star does not appear to move in the sky because it is located above the axis of rotation of the earth in the north direction. It appears to remain stationary at a point in the sky.

The following are the physical properties of metal :
- The physical properties make them useful for many purposes. For e.g. Copper is used in making electric wires, gold is used to make jewellery, stainless steel is used to make pots, pans, etc
- Metals react with nonmetals to form ionic bonds. For e.g. Sodium Chloride (NaCl)
- Metals are a good conductor of electricity which means that they can conduct electricity due to the free moving electrons present in them. Copper is used as wiring as it is a good conductor of electricity.
- Metals have high melting points and high boiling points as they have strong metallic bonds.
- All metals are physically lustrous. They have a lustre that makes them shine. Gold is used for making jewellery.
The following are the properties of Nonmetals :
- Nonmetals have high ionization energies.
- They have high electronegativities.
- Nonmetals are insulators which means that they’re poor conductors of electricity.
- They are dull, they do not have lustre like metals.
- Nonmetals are poor conductors of heat. They’re poor thermal conductors.
- They are very weak and brittle. They tend to easily break or shatter.
- Nonmetals have a low density. They’re light for their size.
