The dust re-radiates the shock wave's energy as infrared light. 塵埃在紅外波段重新發射著激波的能量。
Using the difference of the visible light and near infrared band reflectance,the water bodies can be extracted from remote sensing data. 利用可見光和近紅外波段的地物光譜反射率差異可以從遙感數據中提取水體。
The range of the spectrum in which heat is radiated mostly lies within the infrared portion. 輻射熱的光譜段大部分落在紅外區。
At infrared wavelenths the region is less opaque, and cool protostars are expected to emit most of their energy in the infrared. 在紅外波長範圍，暗雲區是較透明的，而冷的原恆星應在紅外區發射其能量的大部分。
