提出问题:
阳光下树阴中得光斑是怎样形成的?
(2)建立假设:
1、可能透过光的孔通常为圆形,使地面上的光斑也是圆形的。
2可能是因为透光的孔的大小影响光斑的形状
3、可能与透过光的孔距地面的远近有关
(4)得出结论:
树阴下的光斑是太阳的实像,和孔的形状无关 ,其实就是小孔成像...

给你做了两个假设:
2.透光孔也可能时不规则形状,使地面的光斑也是不规则形状;
3.透光孔的形状和光斑的形状是相相反的。
结论: 请用小孔成像的结论。我要全部学物理不是这样学的,已经很明显了,自己想一下,第一个剪成圆形,第二个你自己看怎么剪。 第三小孔成像是一个倒立实像,什么是倒立啊。 你先自己写我看看吧。别人都写了,自己不想,是不会进步的。...
