问题 Orange has a wave length longer than that of green.
Light travels in waves. Every color we see is determined by the length of those waves. Red wavelengths are the longest, and as you go through the rainbow the waves get shorter and shorter until you reach the blues and violets, which are the smallest.
选项 A、True
B、False
答案 A
解析 语义辨析及特定信息的找寻与判断。根据原文“Red wavelengths are the longest … go through the rainbow the waves get shorter … blues and violets, which are the smallest”可知，从红光到紫光波长逐渐减小。题干涉及的两种颜色的光分别为橙光和绿光，根据彩虹颜色的排列，橙光更接近红光，而绿光更接近紫光，所以橙光波长大于绿光。因此，该题的说法是正确的。
