		<description><![CDATA[放大镜的形状是两边薄，中间厚。光线通过它的时候会发生折射，聚到一点上，我们把这一点叫焦点。用放大镜看东西时，如果我们的眼睛正好在这个焦点上，从物体来的光线经过折射后进到眼睛里， 眼睛就会以为光线是从远方直接射进来的， 使我们觉得这个物体比原来大了许多。使用放大镜观察物体的时候，首先要使物体和镜面保持平行。然后调整放大镜和物体间的距离，直到要看的物体十分清楚时为止。这时，我们的眼睛正好是在放大镜的焦点上。另外，千万不要用放大镜看太阳。因为放大镜能把阳光聚集在一起，温度很高，会把眼睛烫伤。 相关文章为什么放大镜不能把角放大？(0) 最新评论<table class="wumii-related-items" cellspacing="0" cellpadding="3" border="0"  style="clear: both;">

		<description><![CDATA[放大镜可以把东西放大，可是，有一件东西它却无论如何也放大不了，这就是几何里面所讲到的“角”。这是为什么呢？一个角是由两条射线组成的，角度的大小就由这两条射线的位置，即张开的程度所决定。角经放大镜放大以后，这两条射线的粗细和长短被放大了，但张开的程度不会改变，角度仍旧不变。所以，放大镜只能把东西的各部分成比例地放大,而形状不变。在数学上，成比例地放大后的图形与原来的图形，被称为是“相似形”，相似形的对应边成比例，而对应角却是相等的。 相关文章放大镜是怎样把物体放大的？(0) 最新评论<table class="wumii-related-items" cellspacing="0" cellpadding="3" border="0"  style="clear: both;">
