What is the typical wavelength of infrared radiation?

Answer 1

There isn't a correct answer to this as it is relative to the object you are observing.

Infra-red radiation is typically understood to be light ranging from 700nm through to around 1mm. Items such as the Sun emit radiation across the visible and infra-red spectrum.

Humans typically radiate heat at the range of around 10 microns.

Answer 2

Good question...I would like to know too!Please help us answer this question!!!

Wavelength: 7.5 × 10-7m to 10-3m, 300megahz to 400 terrahz

Sources: All hot bodies.

Detection: Photographic plates, heat sensitive detectors (eg, thermometers), thermopiles.

Wavelength of Infrared ray is from 10 ^ -6 to 10 ^ -3 (m)

while the wavelength of visible ray is from 10 ^ -7 to 10 ^ -6 (m)

Answer 3

1 x 1012 - 4.3 x 1014 Hz

the frequency is 300 to 400 thz (tera hertz).

the wave length is 1mm to .0008mm

Answer 4

The wavelength is between 700 nanometers and 1millimeter.

Thank you!!

Answer 5

The wavelength range in the infrared spectrum is 1 nm - 750 nm

Answer 6

800 nm and longer

Answer 7

0.74 µm extending to 300 µm.
