They could if they were a source of it. Say if you heated a shiny steel pan in the oven. However shiny objects typically reflect IR better that emitting it. Dark objects are better at absorbing and emitting IR.
its because the drop of the water is like a concave lens
Highly polished, shiny surfaces reflect light the best as they are REFLECTive. White or bright surfaces also reflect light well. Dull, Matt surfaces are the worst reflecters of light
Most car radiators are black as black radiates heat more efficiently than any other color.
A light colored or highly polished metallic surface will reflect a lot of heat (which is primarily infrared radiation). Some people in sunny places put a folding windshield screen up inside their car. The best ones have what looks like shiny aluminum foil on them to reflect the heat.
when a car is filled with gas,it will EMIT a clear vaporThe bulb began to emit a dull radiance.Black smoke began to emit from under the hood as soon as I got onto the highway.Well, the word "emit" is a verb, and generally has to do with gases.For example, "A car emits gas when used by the driver."Another example might be, "A factory can emit gas through the chimney."Dogs can sense when people are nervous or frightened, because of the pheromones (chemicals) humans '''emit''' when they experience these emotions.I would like to emit myself to puerto rico.I heard him emit one shrill cry and then he was silent.
Matte (dull) and black surfaces emit infrared radiation at a faster rate than shiny and white surfaces.
Because, shiny surfaces reflect heat, they don't emit much heat and they don't absorb much heat!

Dull silver surfaces and shiny white surfaces can have different emissivity values, which means they might not emit the same amount of thermal radiation. Emissivity is a property that quantifies how effectively an object emits thermal radiation compared to a perfect blackbody at the same temperature. A blackbody has an emissivity of 1, and objects with emissivity closer to 1 are better emitters of thermal radiation. Dull surfaces, including dull silver surfaces, typically have higher emissivity compared to shiny surfaces. Shiny surfaces often have lower emissivity because their smooth and reflective nature reduces their ability to emit thermal radiation effectively. White surfaces can vary in terms of their shininess and emissivity. A shiny white surface might have a lower emissivity, while a more matte or dull white surface may have a higher emissivity. Therefore, if the dull silver surface has a higher emissivity compared to the shiny white surface, it will emit more thermal radiation than the shiny white surface at the same temperature. However, it's important to note that the exact emissivity values can vary based on the specific properties and conditions of the surfaces, so it's best to refer to specific emissivity measurements for accurate comparisons.
They emit infrared radiation
Infrared radiation.
yes, humans emit infrared radiation
Dull black surfaces they are also best at absorbing it as well. [Shiny and silvery or white surfaces are poor radiators and absorbers of heat. However they are very good in reflecting heat radiation.]
All objects and living things emit infrared radiation unless the object is not a black hole as well unless its temperature is not at the Absolute Zero ( I would call it an "infrared black hole") - such an object can only absorb infrared radiation.
Because plutonium is hot emit also infrared radiation.
The infrared quartz heaters have the infrared emitters and they emit infrared rays continuously to heat the heater in the instrument. The heat is generated and infrared emission stops.
because the light bounces off the flat and shiny surfaces.
