What wave does infrared use?

Infrared radiation is an electromagnetic wave.


Does your hand emit long or short wave radiation and how do you know?

Long wave radiation in the form of infrared waves. These can be seen with an infrared camera.


What type of em wave raditiation is a type of heat wave?

Heat radiation is mainly associated with infrared radiation.


What determines if an electromagnetic wave emitted from an object is a visible light wave or a wave of infrared radia?

The wavelength of the electromagnetic wave determines whether it is visible light or infrared radiation. Visible light has shorter wavelengths than infrared radiation. The range of wavelengths for visible light is approximately 400-700 nanometers, while infrared radiation has longer wavelengths ranging from 700 nanometers to 1 millimeter.


Which type of electromagnetic wave is used to produce a thermogram?

To produce thermogram it needs infrared wave. It is a radiant energy which cannot be seen by naked eyes and it was discovered by Sir William Herschel, an astronomer in the year 1800.


What type of radiation from Earth is the long-wave radiation absorbed by greenhouse gases?

The long-wave radiation absorbed by greenhouse gases is primarily in the form of infrared radiation. After the Earth's surface absorbs solar energy, it re-emits this energy as infrared radiation, which has longer wavelengths compared to the short-wave radiation from the sun. Greenhouse gases in the atmosphere, such as carbon dioxide and methane, absorb and re-radiate this infrared radiation, contributing to the greenhouse effect and warming the planet.


What wave does a heat lamp use?

A heat lamp emits infrared radiation, which is a type of electromagnetic wave. Infrared radiation has longer wavelengths than visible light, and it is often used to provide heat in various applications such as in heat lamps or infrared saunas.


Why does earths atmostsphere have the ability to block outgoing long wave infrared radiation after allowing incoming short waves pass through?

The earth's atmosphere/plasma acts as a reflector for long wave infrared radiation.


The heat which radiates outward from the Earth's surface is transformed into -wave radiation.?

infrared


What electromanetic wave can you detect with your skin?

You can detect infrared radiation, which is a type of electromagnetic wave, with your skin. Infrared radiation is typically felt as heat and is responsible for the sensation of warmth when you are near a hot object or under direct sunlight.


What type of wave that is emitted by all warm bodies?

Infrared radiation is the type of wave emitted by all warm bodies. This type of electromagnetic radiation has wavelengths longer than visible light and is commonly associated with heat.


Which type of electromagnetic wave does a thermogram portray?

A thermogram portrays infrared radiation, which is a type of electromagnetic wave that is invisible to the human eye but can be detected by special cameras to create thermal images of objects based on their temperature.
