2016年8月10日 · What are Infrared Waves? Infrared waves, or infrared light, are part of the electromagnetic spectrum. People encounter Infrared waves every day; the human eye cannot see it, but humans can detect it as heat. A remote control uses light waves just beyond the visible spectrum of light—infrared light waves—to change channels on your TV.

2016年8月10日 · NEAR INFRARED RADIATION. A portion of radiation that is just beyond the visible spectrum is referred to as near-infrared. Rather than studying an object’s emission of infrared, scientists can study how objects reflect, transmit, and absorb the Sun’s near-infrared radiation to observe health of vegetation and soil composition. HEALTHY VEGETATION

2016年8月10日 · Electromagnetic energy travels in waves and spans a broad spectrum from very long radio waves to very short gamma rays. The human eye can only detect only a small portion of this spectrum called visible light.

2025年1月21日 · Infrared-light wavelengths are longer and more likely to slip between particles. In space, this allows infrared wavelengths to penetrate all but the densest regions of dust. By viewing infrared light, we can essentially look through cosmic clouds of gas and dust to the objects behind and within them.

2024年11月3日 · Infrared Waves: Light waves just beyond the visible spectrum of light are infrared light waves. They range from near-infrared like what are used in remote controls, to far-infrared which can be sensed as heat.

2016年8月10日 · Ultraviolet (UV) light has shorter wavelengths than visible light. Although UV waves are invisible to the human eye, some insects, such as bumblebees, can see them. This is similar to how a dog can hear the sound of a whistle just outside the hearing range of humans. ULTRAVIOLET LIGHT FROM OUR SUN

2016年8月10日 · The heat generated by this absorption is emitted as longwave infrared radiation, some of which radiates out into space. ABSORBED ENERGY. The solar radiation that passes through Earth’s atmosphere is either reflected off snow, ice, or other surfaces or is absorbed by the Earth’s surface.

2016年8月10日 · The radio astronomy instrument called WAVES on the WIND spacecraft recorded a day of bursts of radio waves from the Sun’s corona and planets in our solar system. Data pictured below show emissions from a variety of sources including radio bursts from the Sun, the Earth, and even from Jupiter’s ionosphere whose wavelengths measure about ...

2016年8月10日 · Wave Behaviors. Light waves across the electromagnetic spectrum behave in similar ways. When a light wave encounters an object, they are either transmitted, reflected, absorbed, refracted, polarized, diffracted, or scattered depending on the composition of the object and the wavelength of the light.

2016年8月10日 · Microwaves are a portion or “band” found at the higher frequency end of the radio spectrum, but they are commonly distinguished from radio waves because of the technologies used to access them. Different wavelengths of microwaves (grouped into “sub-bands”) provide different information to scientists.
