What is infrared light used for?
What are the special features of infrared lights?
They emit infrared light waves. Which is a non-visible light. Commonly used to provide light for infrared security cameras when there in little to no light visible light Also used in bathroom heat lamps to transmit the heat waves to your skin I believe (not sure) infrared is lower frequency than visible light and ultraviolet is higher frequency than visible light

What are the infrared light used for?
Infrared light has a large range of applications, and is often utilized where visible light cannot be detected, or something is blocking visible light but does not block infrared light. For example, when looking toward the center of the Milky Way large amounts of dust obscure the visible light that emanates from the center of the galaxy. This dust though does not obscure infrared light at certain wavelengths, and so astronomers can use cameras that are sensitive to this infrared light to obtain a picture of this region of space. Infrared light is also used in thermal imaging systems, and night-vision instruments are often sensitive to the infrared wavelengths that are emitted by warm objects.

What is infrared used for?
Infrared light is a type of electromagnetic radiation. Its wavelength is longer than that of visible light, making it invisible to the naked eye unless special equipment and filters are used. Infrared Cameras Thermography is a technology that allows cameras and other equipment to pick up infrared light emitted by an object in the form of heat. It is especially useful in determining the temperature of images and can be used to locate marijuana inside a house, as high temperatures are required for its growth. Military Use Infrared light is used extensively in the military. Night-vision cameras and goggles are useful for soldiers, and infrared light can be used for surveillance and tracking of objects. Meteorology Weather patterns can be tracked with the use of infrared light sensors that detect changes in the temperature of water and cloud formations. Heat Infrared lights are frequently used in restaurants to keep food warm. Infrared light is warmer than visible light and keeps food hot for longer periods of time, especially when in close range. Considerations Eye protection is needed in industries that use infrared light extensively, as the light can cause temporary or permanent vision damage.

Where can you find an infrared LED light?
A infrared LED is an LEd which emitts light of wavelength greater than the wavelength of red light however human eyes cannot sense or see infrared light. these LED's are used at the tip of many remote control equipments used to switch channels of a television. An infrared receiver is present in the television set and accordingly the channel/volume etc changes.

How does infrared light reflect off objects?
Infrared radiation or light is part of the electromagnetic spectrum and acts the same as visible light does. Infrared can be absorbed and reflected by objects much the same way as visible light. More on Infrared: Some black objects that absorb visible light radiation may reflect infrared. Much of the absorbed visible light energy is re-emitted as infrared up to many hours later. There are subcategories of infrared, two common ones are near-infrared and far-infrared. Near being closer to visible light.

What are infrared light waves?
== == Infrared light lies between the visible and microwave portions of the electromagnetic spectrum. Infrared light has a range of wavelengths, just like visible light has wavelengths that range from red light to violet. "Near infrared" light is closest in wavelength to visible light and "far infrared" is closer to the microwave region of the electromagnetic spectrum. The longer, far infrared wavelengths are about the size of a pin head and the shorter, near infrared ones are the size of cells, or are microscopic.
What would be the hardest to see in infrared light?
Is the frequency of infrared light higher than visible light?
Asked in Physics
Where does infrared heat come from?
Infrared lies between the visible and microwave portions of the electromagnetic spectrum. Infrared waves that are near to visible light do not generate heat and are used in TV remote controls. Infrared waves that are far from the visible end of the light spectrum are thermal and generate heat. The infrared heat from the sun, a lamp or a radiator is a type of far infrared radiation.
