Sometimes we tend to see a very faint image of ourselves in a transparent glass sheet. Which property of glass sheet can be highlighted by this observation?
Glass reflects a small part of the light rays falling on it.
Image formation of an object takes place when light rays from the object falls on a reflecting surface, gets reflected, and then fall on our eyes. If we see a faint image of ourselves in a glass sheet, then that can only happen if the sheet is reflecting a part of incident rays just like a plane mirror does. If the sheet reflects a larger part of the incident rays then we would rather see a clearer image, so the statement of the second option cannot be correct. Thus, the statement of the third option is the only correct statement.
