SSC MTS EXAM

Detailed explanation-1: -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.

Detailed explanation-2: -Infrared signals are used in certain types of data communication including television remote controls. IR radiation is used for heating in both industrial and consumer processes. In addition to night vision goggles, IR radiation has several uses in military devices for missile guidance, homing and heat seeking.

Detailed explanation-3: -Infrared heats people, floors, walls, and other surfaces directly without heating the air first. The result is an instant warming effect, similar to the effect felt when the sun emerges from the clouds on a chilly day.

Detailed explanation-4: -Specifically, the infrared radiation is absorbed by greenhouse gases that re-radiate the infrared waves out in all directions-some into space and some back to Earth . The infrared radiation that is radiated back to Earth causes further warming at the surface and lower atmosphere .
