How hot is infrared radiation?
Infrared radiation is sometimes referred to as thermal radiation. The temperature of infrared radiation varies from object to object. All objects radiate infrared, even objects at room temperature and frozen objects.
What type of radiation does earth's surface radiate to cool down?
Longwave (mostly infrared)
What types of objects emit of infrared raditation?
Any object emits infrared radiation. The hotter the object, the more infrared is emitted.
What materials radiate heat?
All materials radiate heat equivalent to their temperature above absolute zero.This heat is called "black body" radiation. When the peak of the "black body" radiation from a material is in the infrared band we perceive it as heat, but the radiation is always radiant heat regardless of whether it peak is in the radio band, infrared band, visible band, ultraviolet band, x-ray band, etc.
What does the earth do with the radiation that reaches us?
Part of the radiation is immediately radiated back into space. The remainder is absorbed; most of what is absorbed will be radiated back into space soon (as the materials heat up, they radiate out more infrared radiation).
Why are carbon dioxide and water vapor called selective absorbers?
Any object that can specifically absorb and emit radiation (in the form of, say, infrared radiation), is called a selective absorbers. An example is: Snow. It is a good absorber of infrared radiation but poor absorber of sunligh. Object that selectively absorb radiation at some wavelength tend to radiate radiation at that same wavelength. CO2 and water vapors are both very good absorber of infrared radiation but at the same time poor absorber of different forms of solar radiation that are visible to us.
To give out radiation?
To give out radiation is to radiate.
What type of radiation is trapped on earth's surface by the greenhouse effect?
terestrial
A newly formed protostar will radiate primarily at which wavelength?
infrared
A newly former protostar will radiate primarily at which wavelength?
Infrared
A heat lamp produces what radiation?
Heat travels in the form of infrared radiation. You don't use radiation todetect radiation. You use a detector that responds to the type of radiationyou're trying to detect. In the case of infrared radiation, your skin makes anexcellent detector.
How do you know if a star is a protostar?
If you can see it, its a star. Protostars radiate only in the infrared.
