Other species can detect other portions of the electromagnetic spectrum. For instance, honeybees can see light in the ultraviolet range (Wakakuwa, Stavenga, & Arikawa, 2007), and some snakes can detect infrared radiation in addition to more traditional visual light cues (Chen, Deng, Brauth, Ding, & Tang, 2012; Hartline, Kass, & Loop, 1978).Other species can detect other portions of the electromagnetic spectrum.

Light used to "see" an object must have a wavelength about the same size as or smaller than the object. The ALS generates light in the far ultraviolet and soft x-ray regions, which span the wavelengths suited to studying molecules and atoms.The electromagnetic spectrum covers a wide range of wavelengths and photon energies.

Birds can also see the ultraviolet rays which ranges from (300 to 400 nm). The animals that can see the ultraviolet lights cannot see the red light or any shades of red. The visible spectrum of bees ends at 590 nm just before the orange wavelength starts. Although not as far as humans, birds can see some red lights.Humans see light in wavelengths from approximately 390 to 750 nanometers (nm). These wavelengths represent the spectrum of colors we can see. Bees, like many insects, see from approximately 300 to 650 nm. That means they can't see the color red, but they can see in the ultraviolet spectrum (which humans cannot).Our eyes can see only this very narrow band. Since this narrow band of wavelengths is visible to humans we refer to it as the visible light spectrum. The term "light," refers to a type of electromagnetic wave that stimulates the retina of our eyes. Thus, we are referring to visible light, a small spectrum of the enormous range of frequencies ofOther species can detect other portions of the electromagnetic spectrum. For instance, honeybees can see light in the ultraviolet range (Wakakuwa, Stavenga, & Arikawa, 2007), and some snakes can detect infrared radiation in addition to more traditional visual light cues (Chen, Deng, Brauth, Ding, & Tang, 2012; Hartline, Kass, & Loop, 1978).

Electromagnetic Spectrum

Other species can detect other portions of the electromagnetic spectrum. For instance, honeybees can see light in the ultraviolet range (Wakakuwa, Stavenga, & Arikawa, 2007), and some snakes can detect infrared radiation in addition to more traditional visual light cues (Chen, Deng, Brauth, Ding, & Tang, 2012; Hartline, Kass, & Loop, 1978).Electromagnetic radiation in this range of wavelengths is called visible light or simply light. Many species can see wavelengths that fall outside the visible spectrum. Bees and many other insects...Bees see light between 600 and 300nm. This means that they miss some visible light (between 600 and 700nm), but they also gain some ultraviolet light (between 300 and 400nm). The segment of the visible spectrum that they're missing is red.However, some animals have a different visible range, often extending into the infrared range (wavelength greater than 700 nanometers) or ultraviolet (wavelength less than 380 nanometers). 3 For example, bees can see ultraviolet light, which is used by flowers to attract pollinators.Other species can detect other portions of the electromagnetic spectrum. For instance, honeybees can see light in the ultraviolet range (Wakakuwa, Stavenga, & Arikawa, 2007), and some snakes can detect infrared radiation in addition to more traditional visual light cues (Chen, Deng, Brauth, Ding, & Tang, 2012; Hartline, Kass, & Loop, 1978).

The visible spectrum is the portion of the better electromagnetic spectrum that we can see. As Figure shows, the electromagnetic spectrum encompasses all of the electromagnetic radiation that occurs in the environment and contains gamma rays, x-rays, ultraviolet light, visible light, infrared light, microwaves, and radio waves. The visual spectrum in humans is associated with wavelengths that range from 380 to 740 nm—an excessively small distance, since a nanometer (nm) is one billionth of a meter. Other species can detect other parts of the electromagnetic spectrum. For example, honeybees can see light in the ultraviolet range (Wakakuwa, Stavenga, & Arikawa, 2007), and some snakes can discover infrared radiation in addition to extra traditional visible light cues (Chen, Deng, Brauth, Ding, & Tang, 2012; Hartline, Kass, & Loop, 1978).

Light this is visual to humans makes up just a small portion of the electromagnetic spectrum.

In humans, light wavelength is related to belief of color (Figure). Within the visual spectrum, our enjoy of crimson is related to longer wavelengths, vegetables are intermediate, and blues and violets are shorter in wavelength. (An simple manner to keep in mind that is the mnemonic ROYGBIV: pink, orange, yellow, inexperienced, blue, indigo, violet.) The amplitude of light waves is associated with our experience of brightness or depth of color, with better amplitudes appearing brighter.

Different wavelengths of light are associated with our perception of other colours. (credit: modification of paintings via Johannes Ahlmann)
