在平面镜成像实验中,通过“水淹蜡烛”的奇怪现象激发学生的兴趣:转盘上竖直放一块平板玻璃,玻璃前放一支点燃的蜡烛,玻璃后的某一位置放一只透明的杯子。调节转盘使学生通过玻璃清晰地看到杯中也有一支“点燃”的蜡烛。往杯中倒水,当水面漫过烛焰时,发现烛焰并没有熄灭。 In the plane mirror imaging experiment, students' interest is excited by the strange phenomenon of “flooding the candle ”: put a flat glass on the turntable vertically, put a lit candle in front of the glass, put a transparent Cup. Adjust the dial so that students can see through the glass clearly that the cup also has a “lit” candle. Pour water into the cup, when the water over the candle flame, candle flame did not go out.
