• Bonding

• Pneumonoultramicroscopicsilicovolcanoconiosis ( silicosis )

• Refraction

• Lateral Inversion

An inverted image can be seen in a convex mirror,

• under no circumstances

• when the object is very far from the mirror

• when the object is at a distance equal to the radius of curvature of the mirror

• when the distance of the object from the mirror is equal to the focal length of the mirror

An object of length 5 cm is placed at a distance of 20 cm in front of a plane mirror. The size and position will be

• 5 cm high and 20 cm behind the mirror

• 5 cm high and 20 cm in front of mirror

• 5 cm high and 10 cm behind the mirror

• 3 cm high and 20 cm behind the mirror

In order to be used as mirrors, glasses are coated with

• silver

• copper

• platinum

• aluminium

If you are standing 2m away from a plane mirror the distance between you and your image are

• 2m

• 4m

• 6m

• 8m
