分光反射率和植物物体的颜色是由于它对被照射的和特定波长的阳光,有不同的反射所产生的视觉反映。因此,地面上万紫千红的各种色调,是不同波长阳光反射的结果。在电磁波谱中,可见光、红外线、微波等都有反射作用,但它们的分光反射率各自不同,这是 Spectral reflectance and the color of a plant object are due to the visual reflections that are produced by the different reflections of the illuminated and specific wavelengths of sunlight. As a result, the various hues on the ground are the result of the different wavelengths of sunlight reflected. In the electromagnetic spectrum, visible light, infrared, microwave, etc. have a reflection, but their spectral reflectivity are different, which is
