I looked it up in my physics text book and it says that the wavelength is too long to be seen by the human eye.
it is longer than normal visible light
The wavelength of infra-red light is LONGER than the wavelength of red light, and longer than anything to which the eye responds.

no, the wavelength of infrared light is too long for it too be seen. visible light makes up only a small portion of the electromagnetic spectrum
No. Some are longer trhan others, but they are all very short. Light visible to the human eye has wavelengths ranging from a little more than 100 micrometers (infrared) to less than 1 nanometers (ultraviolet). In reference to visible light, infrared is referred to as long wavelength and ultraviolet as short wavelength light. I can't remember the units, but the human visible area is from about 400 (deep blue) to 700 (red), so a rather more restricted range than implied above. All those wavelengths are indeed very short.
To demonstrate the phenomena of diffration in light,the wavelength must be smaller than wavelength of light,which is very difficult,because ligth has very short wavelength.

wavelength and frequency. ultravoilet light has a short wave length and therefore a high frequency, while infrared light has a longer wave length and lower frequency

Infrared is just a colour of light, but one that our eyes cannot see. You can think of the different colours of light as having different wavelengths. Our eyes can see light with wavelengths between blue (short wavelength) and red (long wavelength). Infrared has an even longer wavelength than red light, but our eyes can't see it. If you hold your hand up to a fire, it feels warm. This is beause very long wavelength infrared warms you up. An infrared ray is invisible to your eye, but technologists can build sensors that can detect it. When you use your TV remote control to change a channel on a TV, selecting the channel on the remote tells the device to send out infrared light of a particular frequency. The light from the remote control (invisible to us) is picked up by a sensor on a TV, and depending on the frequency of the infrared, the TV decides what channel to select.
It's true! Shorter wavelengths equate to bluer light, while redder light comes from longer wavelengths. However, if the wavelength of the light becomes too long or too short, the light becomes ultra violet or infrared, meaning they become invisible.
Scattering of light
NO, THE FREQUENCY OF INFRARED LIGHT IS TOO SLOW (WITH CONCOMITANT LONG WAVE LENGTHS) TO EXCITE THE NERVES IN THE RETINAS OF THE EYES. INFRARED RADIATION IS ONE FORM OF ENERGY FROM THE SUN THAT IS ABSORBED BY THE WHOLE BODY. No, heat doesn't appear red to the naked human eye, because infrared light isn't in the visible spectrum of colors that humans can see. Heat's wavelengths are too short for the naked eye to detect, just like ultraviolet's wavelengths are too long for the nake eye to also detect. However, your skin can detect infrared light and respond to it by sweating when it's absorbing too much heat.
