Now there are candles, some pins, and the flat mirror is replaced by a mirror. How to locate the image? Request to speak

According to the imaging law of plane mirror: What is the imaging size of plane mirror? It is equal to the size of the object, the distance between the image and the object and the plane mirror is equal, and the connecting line between the image and the object is perpendicular to the mirror. The imaging law of plane mirror can also be expressed as: the image formed by plane mirror is symmetrical with the object about the mirror surface.

Experimental steps: 1. Spread white paper on the table, put the flat glass vertically on the white paper, and record the position of the glass plate on the paper. 2. Put the lighted candle in front of the glass plate. 3. Move the pin so that it coincides with the image of the lighted candle behind the glass plate. 4. The position of the pin is the imaging position of the candle.
