Infrared radiation can heat up glass by increasing the kinetic energy of its molecules, causing the temperature of the glass to rise. Glass is not a good conductor of heat, so it tends to retain the heat absorbed from infrared radiation for a longer period of time compared to other materials.
Technically no. Temperature is effectively the average speed of the particles. If you don't have any particles then you have no temperature. Although an Infra-red detector would work, and Infra-red radiation causes heating, that would not be the temperature. Also, this is all theoretical anyway since total vacuums do not exist.
Infrared radiation travels in electromagnetic waves, similar to visible light. It is part of the electromagnetic spectrum and has longer wavelengths than visible light, allowing it to pass through many materials like glass and certain plastics. Infrared radiation is typically emitted by objects due to their temperature.
Infrared radiation is directly proportional to an object's temperature, according to Planck's law. As temperature increases, the intensity of infrared radiation emitted by an object also increases. This relationship is described by the Stefan-Boltzmann law.
Infrared waves were discovered by Sir William Herschel in 1800. Herschel observed that the temperature increased as he passed sunlight through a prism and a thermometer placed beyond the red end of the visible spectrum.
Infrared radiation is used by sensors to detect differences in temperature. Infrared sensors detect the thermal energy emitted by objects in the form of infrared radiation, which allows them to measure temperature variances without physical contact.

Infra-red is the clasic example (the green house effect).

Yes, up to a point all Glass windows block some degree of UV, incidentally normal (not sunglass type) eyeglasses block from 75% of available UV which is harmful. This also explains why there are no real Infra-red or UV burn hazards (in normal operation) with Fish tanks which nmay have Infra-red heaters or UV backlighting, the glass absorbs it!
Infra-Blue was created in 1991.
Infra-Worlders was created in 1973.

Infrared radiation is typically emitted by objects due to their temperature.
The percentage of infrared radiation absorbed by glass typically ranges from 20% to 80%, depending on the type of glass and its thickness. Standard window glass, for instance, absorbs a smaller portion of infrared, while specialized glass, such as low-emissivity (Low-E) coatings, can absorb more. Overall, the absorption varies based on factors like wavelength and the specific properties of the glass.
In general, a hotter object will emit more radiation per unit area.
Anything that has a temperature emits IR radiation. Hotter things emit more at a higher frequency. Then they become Red.
