The shortest wavelength of visible light is the wavelength of the last color you can see on the blue end of the rainbow or spectrum.
Color
A monochromatic source is a source of light of a discrete wavelength. White light is a mixture photons with wavlengths from 390 to 750 nm (what the human eye can detect). The monochrmatic light will have a specific wavelength. For example all photons have wavelength 200 nm.
Light waves are an electromagnetic radiation ranging in and wavelength. Only the wavelengths in between about 4,000 (violet) to about 7,700 (red) angstroms can be perceived by the human eye and is called visible light. The wave itself is too fast and too small to be viewed in an isolated manner. However, all light perceived by the Human eye is a light wave.
If you can see the light reflected, then it has hit your eyes, and your brain is processing it as the sense of sight, if you cannot see it, then it has reflected somewhere other than your eyes-IE; back into space, or it is a wavelength of light that the human eye cannot detect.
The shortest wavelength of visible light is the wavelength of the last color you can see on the blue end of the rainbow or spectrum.
Yes, the skin cell is much longer than the wavelength of visible light. The wavelength of visible light is in the range of hundreds of nanometers. Skin cells are much larger.
Electromagnetic radiation having a wavelengths between 380 - 750nm is visible to the normal human eye. This region of the spectrum is called visible light. Radiation of any other wavelength cannot be seen with the naked eye
The human eye is a refractor, but the telescope could be either refractor or a reflector.
Color
Black is not light. Black is the lack of light.
The wavelength of the electromagnetic visible to the naked human eye is light. Light has wavelengths of 460 to 760 nanometers.
light (electromagnetic radiation of a wavelength that is visible to the human eye (about 400–700 nm))
The shortest wavelength that your eye can see produces the last color you can see on the blue end of the 'rainbow'.
That's because light has a wavelength that is fairly small compared to items we can see - the wavelength of visible light is a bit less than a micron (1/1000 millimeter).
A monochromatic source is a source of light of a discrete wavelength. White light is a mixture photons with wavlengths from 390 to 750 nm (what the human eye can detect). The monochrmatic light will have a specific wavelength. For example all photons have wavelength 200 nm.
It affects the color of the light. If you change the wavelength of visible light, you change the light's color. For instance. Red is a wavelength of approximately 650 nanometers. Orange, about 590. Yellow, 570. Green- 510, Blue, 475 nanometers. Indigo is 445 and Violet is about 400. You can see more here: http://eosweb.larc.nasa.gov/EDDOCS/Wavelengths_for_Colors.html#red
