What type of radiation does a comet emit?
Like the planets, comets emit no visible light of their own-they shine by reflected (or reemitted) sunlight.
Does the sun or earth emit light with higher energy?
Only the sun emits radiation in the wavelengths of visible light, which is considerably higher energy than infrared emitted by Earth.
What is thermal infrared imagery?
Electromagnetic radiation in the range 5.6micrometre to 1.0 cm is called thermal infrared range.Green house gases absorb and emit radiation within this range.Green house gases in the earth's atmosphere are water vapour,carbon dioxide,methane,nitrous oxide and ozone
Why are infrared telescopes sometimes more useful than optical telescopes?
A telescope that "sees" in the infrared spectrum sees heat, which with its longer wavelength than regular visible light has an easier time passing through gas and dust and can therefore see details in areas that are blocked from view. It can also see objects that are warm, but not warm enough to emit light by glowing.
What gives off visible light under an ultraviolet light?
== Fluorescence== Fluorescent objects emit visible light when stimulated by ultraviolet light.
How does a fireplace emit radiant energy?
In the form of visible and infrared light from the fire.
What type of radiation does a comet emit?
Like the planets, comets emit no visible light of their own-they shine by reflected (or reemitted) sunlight.
Is light emitting diodes emit visible light when forward biased?
It depends on the particular LED. Some of them emit infrared light. But, yes, emission occurs when forward-biased.
What will happen to the light bulb when you switch off the electric circuit?
There will no longer be current to heat the filament which will then cool and no longer emit visible light. While it is cooling it will continue to emit infrared light for a time.
What kind of electromagnetic radiation do all warm bodies emit?
Warm bodies emit infrared radiation.
What are a characteristics of infared radiation?
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 wavelengths are in heat lamps?
Although they do have some visible light, heat lamps skew towards the infrared end of the spectrum. Heat lamps are designed to emit light in the Near Infrared (.7µm-1.3µm), Middle Infrared (1.3µm-6µm), Far Infrared (6µm-40µm), and Far-Far Infrared (40µm-1000µm)
Does the sun or earth emit light with higher energy?
Only the sun emits radiation in the wavelengths of visible light, which is considerably higher energy than infrared emitted by Earth.
Do comets emit light?
No. The light you see from a comet is reflected sunlight.
What radiation emitting from stars to earth?
All forms of electro-magnetic ... the full spectrum from UV to visible light to infrared. Pulsars emit x-rays
What property of waves let us see things which don't emit light?
Our eyes can only see visible light. We can use other technologies such as infrared or ultraviolet sensors, but these use electronics to convert them back into visible light that we can see when they are displayed on the monitor. Sometimes we think we can see infrared radiation or ultraviolet light with our own eyes, but in reality those sources are emitting a small amount of visible light since they are so close to the visible light spectrum.
What is thermal infrared imagery?
Electromagnetic radiation in the range 5.6micrometre to 1.0 cm is called thermal infrared range.Green house gases absorb and emit radiation within this range.Green house gases in the earth's atmosphere are water vapour,carbon dioxide,methane,nitrous oxide and ozone
