The term "infrared" comes from Latin roots: "infra" meaning below and "red" referring to the color red, which has the longest wavelength in the visible light spectrum. Infrared radiation has longer wavelengths than visible light, hence the name.
Human beings cannot naturally perceive infrared radiation, as it falls outside the range of visible light. However, some animals, such as snakes and certain insects, have specialized organs that allow them to detect infrared radiation as a form of thermal vision.
The infrared camera can detect heat signatures that are not visible to the human eye.
Yes, germanium does emit far infrared radiation. Infrared radiation is part of the electromagnetic spectrum, and germanium is known for its semiconducting properties that allow it to emit and detect infrared radiation. This property makes it useful in various applications such as night vision devices and infrared sensors.
The infrared ray was discovered in 1800 by Sir William Herschel
Another name for infrared energy is thermal radiation or heat radiation.
Radiative heat loss.
INFRARED RADIATION is also referred to as Heat Radiation.
The common name for infrared radiation is heat radiation.
Another word for infrared energy is thermal radiation.

In one way or another, Infrared cannot be controlled, I say this because if you expose something to Infrared for too long, that thing could burn. Therefore Infrared is too intense, to defrost food (a delicate thing). This is most probably why Infrared would not be good for defrosting food.
You can send files and music from one phone to another in the space of two minutes with just putting the two phones together and turn the infrared button on.
Both X-rays and infrared waves can penetrate certain materials. X-rays can pass through soft tissues in the body, while infrared waves can pass through glass.
In general, no. You may be able to exploit non-linear properties of the medium through which light is shining, but you cannot stop light using just other light.
