What happens to incoming solar radiation after it is reflected off the surface of the earth?
The wavelength is longer. Energy is re-radiated by the Earth as infrared radiation (heat).
How greenhouse gasses can be absorbed?
Greenhouse gases absorb infra red radiation (heat) coming back up from the warmed earth. They hold this heat, and in turn warm up the air around them, as well as warming the earth's surface again.
Which has the longer wavelength radar or light?
Radar has the longer wavelength.
What sort of wavelengths does infrared radiation have?
Infrared is from about 0.7 microns to maybe 100 microns or so. Visible light runs from about 0.7 (red) to 0.4 microns (purple), so anything longer than that is "infrared" which means "below red". It's a little fuzzier where infrared ends and microwaves begin. 100 microns is one possible definition. Terrestrial radiation peaks at about 10 microns, so that's definitely IR. 300 GHz is 1 mm or 1000 microns, and it's definitely microwaves. Terrahertz radiation is the current no-mans-land between microwaves and infrared, and 1 Terrahertz is 333 microns.
When a wave is passing through a uniform medium and the frequency of this wave increases it wavelength does what?
The wavelength gets longer.
Which form of radiation has the longest wavelength between infrared and visible?
Infrared radiation has longer wavelengths.
What type of electromagnetic wave has a slightly longer wavelength than red light?
Infrared radiation like heat.
What has a wavelength longer then the wavelengths of visible ight?
Infrared radiation.
What is radiation called having wavelength just longer than red light?
Infrared radiation.
What type of electromagnetic radiation has a wavelength next to but longer than visible light?
Infrared radiation.
What type of electromagnetic radiation has a wavelength next to but is longer than visible light?
Infrared is longer.
What electromagnetic wave has a slightly longer wavelength tha red light?
Infrared.
What electromagnetic waves have a wavelength slightly longer than the visible light?
infrared
Infrared light is what?
It is electromagnetic radiation whose wavelength is longer than that of visible light.
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).
Why is microwaves found between infrared and radio waves?
the electromagnetic spectrum (all existing radiation) is organized in order of shortest wavelength from the left to longest wavelength from the right. Infrared waves, felt as heat, are slightly longer than the visible light spectrum, and microwaves longer still, and radio waves longer still.
Does infred waves have the same wavelength as visible light waves?
Infrared radiation is not visible. Its wavelength is longer than red.
