What kind of electromagnetic radiation do all warm bodies emit?
Warm bodies emit infrared radiation.
Examples of infra-red radiation?
At room temperature, any material will emit infrared radiation. A dark object is likely to emit more radiation than a light one.
What happens when carbon monoxide is passed over red hot iron at 120c?
It would cool the iron. Iron is red hot at about 700 C
Who invented the infra red waves?
Will Young invented the Infra Red Waves in 1943
How a toaster uses infra red radiation?
The 'stuff' that comes out of the toaster's red-hot coils and dries the bread and then browns the bread, is infrared radiation.
Where is infra red radiation emmited from?
Hot objects emit infra-red radiation. E.g. the human body.
What is the Infra red?
vibrating molecules relase infra-red radiation (that's hot things)
What is the source of infra-red?
vibrating molecules relase infra-red radiation (that's hot things)
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 type of waves are used in night vision?
Infra red radiation is the best. Usually living bodies would emit IR radiations which could be seen through IR spectroscope or telescope. Though IR are not visible to our eyes those can be recorded on suitable films.
What are the infra red radiation sources?
Anything that has a temperature emits IR radiation. Hotter things emit more at a higher frequency. Then they become Red.
Which will emit the most infra red radiation a glass of milk taken from the fridge or a cup of tea?
In general, a hotter object will emit more radiation per unit area.
What kind of electromagnetic radiation do all warm bodies emit?
Warm bodies emit infrared radiation.
Can you sleep with your bearded dragon overnight?
Yes it will ! Think about it - In their natural environment, the sundisappears at night - leaving them in total darkness ! To maintain the correct temperature - you need a thermostatically controlled infra-red bulb. These emit no visible light, but do emit heat. It should be surrounded by a wire mesh guard to prevent your lizard touching it, as it will get hot !
Why does light attract heat?
It Doesn't!!! Light sources sometimes emit heat as Infra Red radiation which is part of the electromagnetic spectrum, like visible light, but you can't see it. It Doesn't!!! Light sources sometimes emit heat as Infra Red radiation which is part of the electromagnetic spectrum, like visible light, but you can't see it. Light = Energy = Heat = Can make light?
