Do hot objects absorb infrared radiation?
All objects emit (give out) and absorb (take in) thermal radiation, which is also called infrared radiation. The hotter an object is, the more infrared radiation it emits. However; the hotter an object, the faster it will emit infrared radiation. Even though hotter objects can absorb infrared radiation, they will continue to emit infrared radiation much faster than they absorb it from any colder objects / sources around them, until an equilibrium is achieved with the objects surroundings i.e. it is always an antagonistic relationship with the objects surroundings and the surroundings with the object.
Why do dark objects absorb and white objects reflect light?
Dark objects absorb wavelengths of energy that are in the visible spectrum of the electromagnetic radiation spectrum. A black shirt has molecules in it thatt absorbs energies of blue and green and all other colors we humans perceive. White light is made from all of the colors combined. A white shirt has atoms and molecules that absorb all the colors of light and release that energy outwards again.
Does infrared radiation cause burns?
yes, the sun emits all types of the electromagnetic spectrum including infra red
Does black absorb or reflect?
Black absorbs radiation. A perfectly black body would absorb all the radiation that is incident upon it.
What are the dangers of infared waves?
Infra red radiation is part of the Eletromagnetic Spectrum, it includes all types of radiation including: Radio waves, microwaves, Infra red radiation, visible light, ultraviolet, x- rays and gamma rays.Infra red radiation risks: it can damage your cornea.

Do all objects radiate energy?
yes. as long at the obj is above absolute 0, it has energy and hence will emit heat. whether there is a net heat gain or loss depends on the environment it is in. yes. as long at the obj is above absolute 0, it has energy and hence will emit heat. whether there is a net heat gain or loss depends on the environment it is in.
Do all molecules absorb infrared radiation?
No all molecules do not absorb infrared radiation. Some of them do.
Do objects absorb water?
Not all objects absorb water
Which layer of the atmosphere does not absorb solar radiation?
Troposphere does not absorb solar radiation. All other layers do not absorb.
How is heat tranferred by radiation?
First of all it is important to note that heat and infra-red rays are NOT the same thing. When an object gets really hot it starts to glow, emitting red light at first, (hence the phrase: 'red hot') because red is the least frequency. Hotter objects emit light of higher frequency. A light bulb and the Sun are both examples of this. But infra-red rays are even lower in frequency than red light. Infra-red rays are emitted in the same way by objects at room temperature. That means you, your computer and everything around you are 'glowing' with this infra-red radiation. Infra-red rays carry energy between objects at the speed of light. This process causes relatively hot objects to cool down faster.

What processes produce the difference colors we see in opaque objects?
Different materials absorb different wavelengths of visible radiation from sources like the sun or light bulbs. The wavelengths that are not absorbed are reflected as visible radiation, and the color we see depends on the wavelength of that reflected light, with a longer wavelength correlating to more reddish colors, and shorter wavelengths with more bluish colors. White objects reflect all of the visible radiation that strike them, which is why they absorb less heat than black objects, which reflect much less visible radiation.
