问题 Harry Potter is mentioned in the passage, because scientists
What is true of microwaves?

选项 A、Their wavelengths are shorter than those of visible light.
B、Their wavelengths are longer than those of visible light.
C、They are different from visible light as they are a kind of radiant energy.
D、They axe visible to the human eye.

答案B

解析 第三段最后一句中告诉我们,A是错误选择,B是正确选择。该段第三句说,微波与可见光一样都是一种辐射能,所以C的说法是错误的,不能选择;根据该段第一句:with waves of light that the human eye can see和第三句:Like visible light,可以得知D是错误的说法,也不能选择。
