They absorb and also scatter more longer-wavelength red hues than shorter-wavelength blues. ... It was an orange haze all over the place.” That’s why the orange light seemed so omnipresent, so ...

Remarkably, the orange light made a big difference in brain activity. The scientists believe that, because orange light has a longer wavelength, it makes the melanopsin more light sensitive, and ...

Sewage-contaminated water absorbs certain wavelengths of light, leaving a signature that can be detected by space-based instruments, a new study finds.

Orange light, which has the longer wavelength, is known to make the pigment more light-sensitive, but blue light has the opposite effect. Green light lies somewhere in the middle.

Most of the time, a material's color stems from its chemical properties. Different atoms and molecules absorb different wavelengths of light; the remaining wavelengths are the "intrinsic colors ...

At a very narrow of temperatures, hot objects will emit visible light (wavelengths from roughly 300 nanometers to about 700 nm). Mind you – and this is critical in a minute – the objects don ...

Sure, it was wildfire smoke that made parts of California and Oregon change hue. But inside that smoke was alchemy — the chemistry and physics of molecules and wavelengths.
