The area below the spectrum has a rainbow pattern from red on the left to purple on the right.

光谱下方的区域有一个彩虹图案，从左边的红色到右边的紫色。

The resulting interference creates a circular rainbow pattern that extends out from the point of contact between the lens and the plate.

由此产生的干涉产生了一个圆形的彩虹图案，该图案从镜头和板之间的接触点向外延伸。
