There's no reason that infrared light should move at a speed different from the speed
of any other wavelength of light, or for that matter, the speed of any other form of
electromagnetic radiation. The speed of infrared light is simply the speed of light in
whatever medium it happens to find itself at the moment.
What else can I help you with?
Which one is faster infra red light or light?
All electromagnetic (EM) radiation travels at the same speed in a vacuum. However in a different medium, for example a glass triangular prism, the speed depends on the frequency of the EM radiation, and on the material it travels through. Generally for transparent materials, infra-red will travel faster than visible light. This frequency dependence of the speed is what causes dispersion and can be seen in rainbows.
Does ultraviolet light have a lower frequency than visible light?
No, ultraviolet light has a higher frequency than visible light. Visible light has wavelengths between about 400 to 700 nanometers, while ultraviolet light has shorter wavelengths below 400 nanometers.
How does heat from the sun reach us?
Sunlight or Solar Radiation is essentially photons, or packets of energy, emmited from the suns surface, which are able to travel through the vacuum of space at the speed of light. This comes to us in a range of wavelengths, including Visible light, Ultra violet and Infra red radiation.
How does the heat from the sun reach your bodies?
The Sun's energy reaches Earth in the form of "electromagnetic radiation". Most of the heat is carried by the visible light, but there are other parts of the "spectrum" of radiation involved such as the infra-red. Much of the heat reaches you after being absorbed by the Earth in various ways and given out again. This heat contains a lot more infra-red than direct sunlight.
What type of electromagnetic radiation does an infrared telescope collect?
infra-red telescope is a telescope in which you can look at everything in the waves of infra-red.
How does the visible spectrum compare the the entire electromagnetic spectrum?
it is slap bang in the midde of the spectrum, with Ultra Violet light on one side, and Infra red on the other. In a vacuum it travels at the same speed as all of the others (the speed of light) UV has a shorter wavelength, and Infra red has a slightly longer one.
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 part of light is heat?
Infra red part of light is responsible for heat.
What band of light is below the visibile spectrum?
Infra Red
Would radioactive isotopes be seen as infra red light?
no
Why do you see a white spot on the camera-display when you make a photo of a remote-control?
Because remote controls use infra red light to communicate with the TV, stereo or what ever the remote is for. Infra red is a type of light we cannot see with our eyes, but cameras and video cameras turn infra red into visible light.
What animal can see uv rays and infra-red light?
Goldfish
What are the em waves that are just below visible light?
Infra red.
What kinds of photography depend upon infrared light?
If you actually mean infra-red light, it is simply infra-red photography. Color and b&w infra-red film as well as filters for electronic flash may still be available from specialty suppliers. If you are referring to images created by recording heat energy emissions, it is not really infra-red photography. That is correctly referred to as thermography.
What is the danger of infrared light?
Infra-red light is heat, so if you have a lot of it, you will suffer from burns...
What colour of light will be absorbed first as the sunlight enters water?
Infra-red
