2400多年前,墨家学派的创始人墨翟和他的学生就做了“小孔成像”的实验,并在《墨经》一书中作正确的解释．在学完“小孔成像”一节后,很多同学饶有兴趣地动手做这个实验．他们在光线较暗的实验室里,把一块钻有小孔的厚纸板放在点燃的蜡烛和光屏之间．按“小孔成像”的规律,本应可以在光屏上看到烛焰倒立的像,但成功的实验并不多．由此同学们提出了一系列问题,下面就一一解答． More than 2,400 years ago, the founder of the Mohism school, Mohism and his students, conducted experiments on “small holes imaging” and explained correctly in the book “The Book of Mood.” After finishing the “Pinhole Imaging” section, many students started this experiment with interest. In a darkened laboratory, they placed a piece of corrugated paperboard between a lit candle and a light screen. According to the law of “hole imaging”, it should be possible to see the inverted image of a candle flame on a light screen, but there are not many successful experiments. As a result, the students raised a series of questions.
