What data do infrared satellites use to create image?
They convert infrared radiation into electrical signals which is then converted into visible light.
Electromagnetic radiation with wavelengths just longer than light is?
Infra-red radiation has a wavelength adjacent to but longer than visible light.
Why does a light shine?
Light itself does not give off heat. Light only gives off heat when it strikes another object. Some of the light's energy can be absorbed by the object. This in turn causes an increase in the vibrational speed of the molecule, which leads to a sort of molecular friction, causing the object to heat up.
When was infrared discovered?
According to NASA infrared radiation was first discovered in 1800, by a British astronomer named William Herschel. In an experiment to measure the difference in temperature between the colors in the visible spectrum, he placed thermometers in the path of light within each color of the visible spectrum. He observed an increase in temperature from blue to red, including an even warmer temperature measurement just beyond the red end of the visible spectrum.
What is Electromagnetic radiation that is emitted from the sun?
The University Corporation for Atomospheric Research's High Altitude Observatory reports, "The light or photons emitted from the Sun cover a broad spectrum from very long wavelengths such as radio to very short wavelengths such as xray." See the related link below for more information.
Do infrared photons or visible photons have longer wavelengths?
Visible radiation: 370-750 nm. Infrared radiation: 750 nm-300 μm These wavelenghts are not long.
Why are the photons that emerge from the Sun's surface visible-light photons and infrared-light photons rather than gamma-ray photons?
Photons do not come in different types like infared-photons etc. they are just the wavelength that the photons are at and nuclear fusion just happens to emit photons at a particular wavelength
In what form solar energy leaves the core of the sun?
visible and invisible light
What living things can see other than the visible light?
Some believe that plants can feel rays other than visible photons. Also, snakes can see the infrared spectrum!
How is infrared radiation different from visible radiation?
Both are examples of electromagnetic radiation. Infrared has a longer wavelength (lower frequency) than visible light. Of course visible light is visible to humans and infrared is not (although long wave Infrared is sensible to humans as heat).
Transfer of energy from the sun to earth's surface?
That is transferred mainly through visible and infrared light.That is transferred mainly through visible and infrared light.That is transferred mainly through visible and infrared light.That is transferred mainly through visible and infrared light.
What is difference between visible and infrared light?
Visible light is visible (for the human eye), infrared is not. Infrared has a longer wavelength, and a higher frequency. visible light is visible to human i.e the VIBGYOR, above vibgyor are ultravoilet light which is not visible to human eye and below vibgyor are infrared light which is also not visible to human eye.
Are mocrowaves a type of infrared waves?
No. Mocrowaves and infrared waves are both different frequency bands of electromagnetic waves. X-rays and visible light are others.
How do visible light and infrared energy warm earth?
The Earth and atmosphere absorb the visible and infrared energy and this warms the earth.
Energy of visible light can be measured in organized packets called?
The energy of visible light can be measured in organized packets called photons. These photons have discrete values of energy, meaning there is exact amounts of energy these have, and don't vary in decimal places.
Which form of radiation has the longest wavelength between infrared and visible?
Infrared radiation has longer wavelengths.
What describes the effects of infrared light in a night vision camera?
Night vision cameras convert ambient light photons into electons. Those electrons are amplified by an electrical and chemical process and converted into visible light.
