Explanation: Is that white arch real? What is being seen is a fogbow, a
reflection of sunlight by water drops similar to a rainbow but without the
colors. The fog itself is not confined to an arch -- the fog is mostly
transparent but relatively uniform. The fogbow shape is created by those
drops with the best angle to divert sunlight to the observer. The fogbow's
relative lack of colors are caused by the relatively smaller water drops.

角度讲这些文章价值不大,一般都没什么引用,但引人入胜,开阔思路,而且包含
范围广,
很多还是定性讨论,甚至还有心理学专业的从心理学角度讨论为什么月亮在天边时看
起来要大些,等等。
附上几篇没什么数学公式的讨论文章,这在applied optics中很少见,有兴趣的可以读
读。 |
