What can be visible or infrared?
What can be visible or infrared? Visible light has a wavelength that ranges from 380 nm – 750 nm on the electromagnetic spectrum while infrared light is just beyond it, ranging from 700 nm – 1 mm, the start of the non-visible portion of the spectrum. As a result, infrared cannot be seen except with […]
Can black light exist?
Can black light exist? A blacklight (or often black light), also referred to as a UV-A light, Wood’s lamp, or ultraviolet light, is a lamp that emits long-wave (UV-A) ultraviolet light and very little visible light. This stands for “blacklight blue”. Why is the flame on my candle so small? There are many potential reasons […]
