Wavelengths

The shortest wavelengths were color-coded blue, the longest wavelengths red, and intermediate wavelengths green.

Short wavelengths, such as blue, scatter more, while longer wavelengths, such as red, scatter less.

The types of radiation that are known to cause cancer, such as gamma rays and x-rays, are much shorter wavelengths than what's caused by cell phones, and those longer wavelengths have never been shown to create cancer risks.

Not only is it made mostly of glass, which is intrinsically biocompatible, the laser can also be excited with longer wavelengths of light and emit at shorter wavelengths.

A standing wave like this can have 0,1,2, or any integer number of wavelengths around the circle, but it cannot have a non-integer number of wavelengths like 8.3.

Because the blue and violet wavelengths are absorbed last compared to the other wavelengths, open ocean waters appear deep-blue to the eye.

Because the Earth's surface is colder than the photosphere of the Sun, it radiates at wavelengths that are much longer than the wavelengths that were absorbed.

Bees' visible spectrum ends at about 590 nm, just before the orange wavelengths start. citation Birds, however, can see some red wavelengths, although not as far into the light spectrum as humans.

Cross-culturally, when people have a word for red, they agree with other cultures on which wavelengths of light best fit the term "red" (the same wavelengths that primarily excite the cone cells which detect red, and the red/green channel to the brain).

Early radars used very long wavelengths that were larger than the targets and thus received a vague signal, where as some modern systems use shorter wavelengths (a few centimeters or less) that can image objects as small as a loaf of bread.

Higher frequencies have shorter wavelengths, and lower frequencies have longer wavelengths.

However, other kinds of magnitude systems do exist based on different wavelengths, some well away from the distribution of the visible wavelengths of light, and this effects the assumed apparent brightness.

However, typica are not as well camouflaged against foliose lichens common on tree trunks; though they are camouflaged in human wavelengths, in ultraviolet wavelengths, foliose lichens do not reflect ultraviolet light.

Increased cloud-column depth increases the albedo at optical wavelengths, but decreases it at some infrared wavelengths.

Light at these wavelengths is absorbed by the Earth's atmosphere, so observations at these wavelengths must be performed from the upper atmosphere or from space.

Light of shorter wavelengths (violet, blue, green) is bent more than that of longer wavelengths (yellow, orange, red) but the violet and blue light is scattered more, leaving light that is perceived as green.

Shorter wavelengths are more likely to be scattered by the air molecules and the small particles, and so by the time the light has passed through the atmosphere, the longer wavelengths dominate.

The brightness of Vega is exceeded by four stars in the night sky at visible wavelengths (and more at infrared wavelengths) as well as bright planets such as Venus, Mars, and Jupiter, and these must be described by negative magnitudes.

The strong wavelength dependence of the scattering (~λ −4 ) means that shorter ( blue ) wavelengths are scattered more strongly than longer ( red ) wavelengths.

The two most commonly used lanthanides in life science assays are shown below along with their corresponding acceptor dye as well as their excitation and emission wavelengths and resultant Stokes shift (separation of excitation and emission wavelengths).
