Are Infrared Heaters more cost efficient than a regular space heater?
Infrared Heaters are generally more cost efficient then regular space heaters. The reason is that they heat the object directly rather then heating the air, so it wastes less engergy. Ive seen estimates that say its as much as 80% more energy efficient.
What are 3 ways that electromagnetic radiation is used to improve your everyday lives?
The first type of a electromagnetic wave is an x - ray it helps us today because it helps us see our bones. The second one is a microwave the microwave it helps us warm our food. The last one is light it helps us see in the dark. ============================== -- Visible light was useful to me today when it enabled me to see things, and avoid bumping into them as I drove my car to the grocery store. -- Infrared radiation from the sun was useful to me because it allowed me to make the trip to the store without a heavy jacket. -- Microwave radiation was directly useful to me when I re-heated my coffee in the radar oven, but it was vastly more useful to me in an indirect way. Microwave radiation, by its very existence, makes it possible for me to earn a living as a microwave engineer.
What part of the electromagnetic spectrum has the most energy?
The waves with higher frequencies have more energy and the gamma rays have the most energy in the electromagnetic spectrum
What is infrared imagery and how is it used?
Infrared imagery measures the amount of heat in a particulare location. It is often used with satilites to watch whether patterns when there is no light or to determine where over shooting tops are forming in a storm. Colder temperatures are typically white, the darker the color the more cold it is. (This is also true for other infrared devices none wether related such as that of detecting body heat.) Different shades of grey can be used to to determine probably could hieghts and types.

Why infrared sensors more useful at night?
Infrared is heat and during the day other objects are hot besides bodies
Which companies produce infrared sensors?
There are many companies that produce infrared sensors. Some companies include Photonics, Sofradir, Infatec, Optics, and many more infrared companies.
Why are infrared rays useful in seach and rescure operations?
infrared can be very helpful at nightime rescues, because infrared allows the user to see body jeat, which can not be seen with night vision goggles. infrared is more efficient only because of its ability to pick up body heat.
How Sunlight Can Impact Your Garage Door Sensor?
Garage door sensors use infrared light. The sun also carries infrared light which, you guessed it, is more powerful than the light of the sensors. If the light of the sun surpasses the infrared sensors light, the sensors might not be able to signal one another. This is why a garage door might stop closing if strong sunlight is shining on the eye of a garage door sensor. For more call us at 678-487-2727
Where online can I find more information about infrared sensors used in automatic doors?
You can find them on braindex.com. You can also try looking on www.tradekey.com.
Is night vision and infrared vision the same?
No, night vision is the ability to see in low light condition and infrared vision is the capability of biological or artificial systems to detect infrared radiation. The terms thermal vision and thermal imaging, are also commonly used in this context since infrared emissions from a body are directly related to their temperature: hotter objects emit more energy in the infrared spectrum than colder ones.
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 CamerasThermography 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 UseInfrared 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.MeteorologyWeather patterns can be tracked with the use of infrared light sensors that detect changes in the temperature of water and cloud formations.HeatInfrared 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.ConsiderationsEye protection is needed in industries that use infrared light extensively, as the light can cause temporary or permanent vision damage.
What are some uses of infrared radiation?
Some ways are:Doctors use infrared lamps to treat skin diseases and relieve the pain of sore muscles. In these treatments, the infrared rays pass through the patient's skin and produce heat.Scientific advances pertaining to infrared have allowed buildings to keep cool even in the summer. Gold transparent films in the windows of large office buildings reflect infrared and help to keep temperatures cool.Photographers use film that is sensitive to infrared rays to take pictures in places where there is no visible light. Burglar alarms also use infrared.Infrared is used extensively in specially-designed ovens for drying painted and enameled surfaces, leather, metals, papers and textiles.
Where can I learn about infra red cameras?
Infrared cameras use heat to create an image, rather than color. People use infrared cameras to take images at night, when color isn't readily visible. Try www.infraredcamerasinc.com for more info.
What is the light source used in most industrial photoelectric sensors?
The light source is typically a diode that emits either visible or infrared light. Other photolelectric sensors use lasers, which emit more coherent beams that scatter less and maintain their brightness over a distance. (see also the related link)
What is the Superlative and comparative to the word useful?
Most useful and more useful.
What is the comparative and superlative forms of useful?
more useful, the most useful
