Look it up now Earth scientists study infrared as the thermal emission (or heat) from our planet. As incident solar radiation hits Earth, some of this energy is absorbed by the atmosphere and the surface, thereby warming the planet. This heat is emitted from Earth in the form of infrared radiation

Infrared radiation is a form of electromagnetic radiation which is found just outside the visible portion of the spectrum, before the color red 1. Infrared radiation is invisible but the energy of this region happens to correspond to the approximate level of energy needed to start molecules moving in various ways Infrared light (IR) is an electromagnetic radiation whose wavelength spans between 780 nm and 1 mm, and it represents the less energetic, although the most abundant part (~54%) of the solar radiation spectrum that reaches the Earth's ground (Fig. 1). It is an invisible radiation, and its main effect on human beings is the nice warmth sensation which most of us appreciate

An infrared heater or heat lamp is a body with a higher temperature which transfers energy to a body with a lower temperature through electromagnetic radiation. Depending on the temperature of the emitting body, the wavelength of the peak of the infrared radiation ranges from 780 nm to 1 mm. No contact or medium between the two bodies is needed for the energy transfer Infrared radiation reflection and fire protection of the substrate are related. Ceramicrete coatings are characteristically very efficient in reflecting the infrared part of the solar spectrum. Informal tests have shown that they reflect as much as 80% of the radiant heat energy with a typical composition of MgO and KH 2 PO 4 Infrared radiation can't be seen but it can be felt as it is one of the natural ways in which heat is transferred, the other 2 are convection and conduction which you will probably have heard about at school.
