一、同时成两个像的疑惑研究凸透镜成像的实验中,当光屏上出现蜡烛倒立的实像时,记下光屏的位置;若拿走光屏,当眼睛在光屏原位置的右方向着透镜方向观察时,仍然会看到光屏原位置处有一个与光屏上原来倒立的实像完全相同的倒立实像;当眼睛在光屏的原位置和透镜之间,向着透镜方向观察时,又会看到蜡烛“正立的像”.于是有同学就认为一个凸透镜可以使物体同时成两个像. First, at the same time into two like doubts Study of convex lens imaging experiment, when the candle appears on the light screen inverted real image, note the location of the light screen; if removed light screen, when the eyes of the light screen in the original position to the right When observing in the direction of the lens, you still see an inverted real image that is exactly the same as the original real image on the screen. When the eyes are looking in the direction of the lens between the original position of the screen and the lens Will see the candle "So, some students think that a convex lens can make the object into two images at the same time.
