It is sometimes called infrared light. Сохраненная копия Похожие Перевести эту страницу INFRARED ENERGY. A remote control uses light waves just beyond the visible spectrum of light— infrared light waves—to change channels on your TV.
This region of the spectrum is divided into near-, mid-, and far-infrared. What is infrared light ?
Here we will learn the story of William Herschel and how he completely by accident. In order to understand night vision, it is important to understand something about light. The amount of energy in a light wave is related to its wavelength: Shorter wavelengths have higher energy. Of visible light , violet has the most energy, and red has the least.
Just next to the visible light spectrum is the infrared spectrum. Near infrared light therapy is an every-day term for the science of photobiomodulation. We experience infrared light every time we feel the heat of the sun on our skin or the warmth of a camp fire.
Technically, what we are experiencing in these instances is thermal infrared light.
Scientists call waves of electromagnetic energy that travel through space light. We tend to think of light as only the radiant energy that . Almost half of the energy arriving to the Earth from the sun comes as infrared light. Anything which has a temperature puts out heat or infrared light. The electromagnetic spectrum spans a wide range of wavelengths from very short wavelength and highly energetic gamma rays to very long wavelength and low-energy radio waves. The visible part of the spectrum is only a small portion.
When we think of light , we may imagine the glare of the Sun on a summer day, or the soft glow of a light bulb at night. But visible light , the only light our eyes can see, makes up just a tiny . The light we see with our eyes is really a very small portion of what is called the Electromagnetic Spectrum. The Electromagnetic Spectrum includes all types of radiation – from the X-rays used at hospitals, to radio waves used for communication, and even the microwaves you cook food with. Infrared is a form of light. From reducing inflammation and pain to improving moo infrared radiation has a variety of benefits.
It can even be used to treat some forms of cancer. This is by far one of my favorite . Investigate infrared electromagnetic radiation by using your television remote control as a source and a digital camera as a detector. Are natural beauty treatments always better?
Radio waves, x-rays, and microwaves are all types of light.

Now, a research group in the Netherlands is proposing to increase wireless capacity by orders of magnitude by using infrared light instead of radio waves.
The light we can see with our eyes is composed of many light rays, each with its own colour—like those of a rainbow.
