When sunlight strikes the Earth, it is … WebWhat band does water reflect? Blue light (450 to 490 nanometers) is among the few wavelengths that water reflects (the rest are absorbed). Hence, blue bands are useful for seeing water surface features and for spotting the sea- or lake floor in shallow waters.
WebInfrared (IR) light—specifically between 6,000 to 7,000 nanometers—is critical for observing water vapor in the atmosphere. Though water vapor makes up just 1 to 4 percent of the atmosphere, it is an important greenhouse gas. It is also the basis for clouds and rainfall. Water vapor absorbs and re-emits energy in this range, so infrared ... WebFeb 22, 2024 · $\begingroup$ In particular, water absorbs more light at the red end of the spectrum than it does at the blue end. Divers (and even more so cameras) see this as progressive loss of red colors in scenery viewed underwater. Eventually, say a thousand feet down in relatively clear ocean water, there is virtually no light left. $\endgroup$ –
WebAnswer (1 of 2): The reflection happens at the surface, where there is a change in the density of the medium (with respect to light, we are talking about Refractive index). This happens for all waves: sound waves will reflect off solid surfaces too (such as walls, to give an echo). You are corre...
WebAug 3, 2012 · Of course, near IR will reflect off the surface, if the angle is right. Unfortunately, the angle needed for that device is almost normal to the surface, and it will not work well for detecting the water's surface level.
