(20 1 1? Suqian) is the scene of "exploring the imaging characteristics of flat mirror" as shown in the figure. (1) In this experiment, although imaging is performed, a transparent glass plate is used instead of a flat mirror. In order to locate the image and make the image of candle A coincide with the image of candle B, both the images of candle A and candle B can be observed, and a transparent glass plate should be used in the experiment.

Choose two candles of the same size and compare the sizes of objects with candle B instead of candle A. 。

The distance from the object image to the plane mirror is equal. If the lighted candle A is far away from the glass plate, the image will be far away from the glass plate.

So the answer is: (1) the location of the image; Compare the sizes of images and objects; (2) stay away.
