Photons in the wavelength range of approximately 0.4-0.8 microns.

The small portion of the electromagnetic energy spectrum the human eye can detect. Visible light includes wavelengths of light from approximately 400 nanometers to 700 nanometers. (A nanometer is one-billionth of a meter.)

the region of the electromagnetic spectrum that is seen by the human eye. Defined by scientists as falling between 390 and 780 nm in wavelength. Visible light contains all of the colors seen in a rainbow: violet, indigo, blue, green, yellow, orange and red. Also known, in scientific circles, as short wave radiation, because the wavelengths involved are shorter than longwave (infra red) radiation.

Electro-magnetic radiation in the visible range - i.e. that which can be detected by the human eye. Typically, the range of visible light extends from around 0.7µm at the red end to 0.35µm at the blue end (one octave, a region in which the frequency doubles from one end to the other). Beyond the red end (and invisible) is Infra Red, beyond the blue end (and thus with a shorter wavelength) is ultra-violet. Visible light is divided into a series of colours - the colours of the spectrum from Red, through Orange, Yellow, Green, Blue and Indigo, to Purple.

That part of the sun's energy that you can see. it is made up of a spectrum of colors; red, orange, yellow, green, blue, and violet. The eye is not equally sensitive to all of these colors. It is most sensitive to yellows and greens which it can see the best. The eye is less sensitive to reds and blues.

the portion of the electromagnetic spectrum visible to the human eye

The portion of the electromagnetic spectrum from about 0.4 µm - 0.8 µm (or 400 - 800 nanometers) This, the portion that we see, is the familiar "spectrum," or rainbow. Violet light represents the shortest wavelengths, and red light the longest.

These are electromagnetic waves found between 400 and 700 nm in length.

The portion of the electromagnetic spectrum that produces light that can be seen. Wavelengths range from 380 to 720 nanometers.

The portion of the electromagnetic spectrum that the human eye can see.

light that can be seen by the human eye

That portion of the electromagnetic spectrum which is detectable by the human eye. The sun emits "white" light, which is all visible colors, but which is only a small part of the entire electromagnetic spectrum. Visible light is energy in the range of approximately 7800 to 3900 Angstroms, where one Angstrom is 0.0000000001 meters. The visible spectrum is most obvious in a rainbow, when the sun's different colors of light are bent (refracted) by the earth's atmosphere during a rainstorm.

Electromagnetic radiation that human eyes can detect; also known as the visible spectrum. The visible colors are red, orange, yellow, green, blue, indigo, and violet, along with various combinations and shades of these colors. Within the visible part of the spectrum, red light has a longer wavelength than blue light.
