Webb常用通信术语缩写解析 WebbIn physics, absorption of electromagnetic radiation is how matter (typically electrons bound in atoms) takes up a photon 's energy — and so transforms electromagnetic energy into internal energy of the absorber (for example, thermal energy ). [1] A notable effect is attenuation, or the gradual reduction of the intensity of light waves as they ...
