What are the wavelength limits for visible spectrum?

The range of visible spectrum is 400nm(Violet) to 700nm(Red).. (1nm = 10-9m)


What is the wavelength of visible spectrum?

roughly in the range of 380 - 750 nanometers


What is the wavelength range of the visible spectrum for electromagnetic radiation?

380nm to 750nm.


The visable range of electromagnetic spectrum is?

The visible range lies from region of wavelength 3800-7600 angstrom.


Is the colour of the ultra violet spectrum violet if not why was it given that name?

The ultraviolet spectrum is 'beyond' (ultra) the violet part of the visible spectrum, that is, beyond the short end of the wavelength range. The infrared spectrum is 'within' (infra) the long end of the wavelength range. The two terms have nothing to do with color, which defines the visible spectrum between violet and red.


Wavelengths in this range of light are those that humans can see?

If it is between 390 and 700nm (nano meter) then yes.


The light that you can see belongs to the visible spectrum?

Yes. All the light we can see is in the visible part of the Electromagnetic spectrum. That is a wavelength range of between about 400 to 700 nanometers.


What does the visible portion of the electromagnetic spectrum fall?

It falls within the following approximate range of frequencies:


What is the frequency range of spectrum?

The range of the visible spectrum is 400THz - 789THz.


How broad is the infrared spectrum?

The infrared spectrum stretches from about 700 nm to about 1 mm wavelength. In terms of the number of frequency doubles (think octave), this range is about 8.9 times the breadth of the visible light spectrum.


How broad is the ultraviolet spectrum?

The ultraviolet spectrum stretches from about 10 nm to about 400 nm wavelength. In terms of the number of frequency doubles (think octave), this range is about 10.8 times the breadth of the visible light spectrum.


How broad is the microwave spectrum?

The microwave spectrum stretches from about 0.1 mm to about 10 cm wavelength. In terms of the number of frequency doubles (think octave), this range is about 12.4 times the breadth of the visible light spectrum.
