IR radiation with wavelengths between 5 and 15 m is sensed as heat and so it is called the thermal infrared region.

Photographic recording of IR radiation is extremely difficult, so scanning spectrophotometers are used instead.

That's just like looking at the immense IR radiation from the earth viewed against the background of space.

The ground gets heated by infrared radiation (IR radiation) that the sun gives off.

Although, the term radiation sounds bad, IR radiation is a good thing.

Although lots of IR radiation is deflected by the atmosphere, enough still gets through to heat the ground and the atmosphere.

But, as soon as the Sun comes back out, so too does the IR radiation warming the earth.

Also, space stations have very good insulation from IR radiation.

After sunset, this thermal energy remains and is emitted in the form of IR radiation.

The IR radiation passes through the dome and then through lenses that focus the energy.
