ICE. You are standing behind ICE wall. I can see you but I can not use a infrared camera for taking your photo. For that matter, ordinary glass does a pretty good job of blocking certain wavelengths of infrared.
Visqueen is mostly transparent in Infrared. Most people aren't surprised that you can see thru "clear" visqueen with an infrared camera, but shocked to find that black visqueen is equally transparent when viewed thru a thermal imaging camera. Many fire departments have Thermal Imaging Cameras. You might be able to drop by a fire station with a sheet of black visqueen to prove it to yourself. You might even surprise the firefighters too!
Cold weather campers often use visqueen when constructing shelters. It will block wind, but will allow the warmth from the sun, or even a campfire to penetrate and trap heat.
nothing Anything that is transparent will have a refractive index. Glass is transparent to visible light and has a refractive index with it. Having these combined properties lets you make a lens for visible light out of glass. Now glass is transparent to IR radiation so any glass lens would focus IR radiation.
It is a spectra that shows how transparent a material can be. in scientific terms, it is incidence of electromagnetic radiation (from the UV, Visible, Infrared wavelength regions) from a source to a material, and there is a detector which records the amount of radiation remaining after the transmission (these radiation that is gone is either reflected of the surface or absorbed by the material). The equipment that measures this is called UV-Vis-NIR spectrometer.
Infrared is directly below, next is x-ray, next is radio.
The closest is infrared radiation.
X-rays have the highest frequency in the electromagnetic spectrum.

Infrared radiation has longer wavelengths.
Ultraviolet and Infrared.

Both are examples of electromagnetic radiation. Infrared has a longer wavelength (lower frequency) than visible light. Of course visible light is visible to humans and infrared is not (although long wave Infrared is sensible to humans as heat).

Infrared is directly below, next is x-ray, next is radio.
Visible radiation: 370-750 nm. Infrared radiation: 750 nm-300 μm These wavelenghts are not long.
