一、黑体与黑的物体不一样黑体,又称绝对黑体,是一个理想化了的物体,它能够吸收外来的全部电磁辐射,并且不会有任何的反射与透射。换句话说,黑体对于任何波长的电磁波的吸收系数为1,透射系数为0。但黑体不见得就是黑色的,即使它没办法反射任何的电磁波,它 First, the black and black objects are not the same Blackbody, also known as absolute blackbody, is an idealized object, it can absorb all the foreign electromagnetic radiation, and will not have any reflection and transmission. In other words, the blackbody has an absorption coefficient of 1 for electromagnetic waves of any wavelength and a transmission coefficient of zero. But the black body is not necessarily black, even though it can not reflect any electromagnetic waves
