WebMar 29, 2024 · Gold beaten into very thin sheets is good at reflecting the lower end of the visible range of the spectrum, which includes red and yellow light. This reflectivity also extends into the infrared range, making gold foil an ideal material for high-performance heat shields. Many components used in spaceflight are coated in gold foil for this reason.

WebNov 2, 2015 · The most popular reflectors are white, silver, and gold (although gold is usually used outdoors, because it adds warm yellow light). So, that leaves silver and white. Which do you use when? Silver reflects much more light, so you’ll use silver when you position the reflector back away from your subject.
