What is a unit of measuring wavelength of light?
The SI unit is meter. But nanometer and angstrom are commonly used units to measure the wavelength of light.
What is the unit of measurement for wavelength of light?
Nanometres. mX10^-9
What is the frequency of a blue light with a wave length of 469 nanometers?
Frequency is in cycles per unit time Wavelength is in length per cycle To convert between the two you need the speed of the wave - which for light is the speed of light - which is given in length per unit time Frequency = Speed of light/Wavelength For a wavelength of 469 nanometers Frequency is 639 Terahertz (THz) or 639,000 Gigahertz (GHz) ... rounded to 3 significant digits since the wavelength is only given to 3 significant digits
What is the wavelength of a wave measured in?
"Wavelength" is described in any convenient unit of length or distance, such as meter, foot, inch, furlong, kilometer, Angstrom, smoot, light-year, etc.
What determine the color of a light wave?
Its wavelength (or frequency).

What is the unit that astronomers most often use to express the wavelength of light?
Speed of light
What are the Frequency and wavelength of visible light?
Light is measured by its wavelength (in Hertz). Wavelength approaches the separation between two progressive wave peaks or troughs. Frequency is the number of peaks or troughs per unit of time.
What is the unit of fluorescence intensity?
The unit of fluorescence intensity is known as FUs. These are unitless and instead shows the light that is emitted from the longer wavelength.
What is the frequency of a blue light with a wave length of 469 nanometers?
Frequency is in cycles per unit time Wavelength is in length per cycle To convert between the two you need the speed of the wave - which for light is the speed of light - which is given in length per unit time Frequency = Speed of light/Wavelength For a wavelength of 469 nanometers Frequency is 639 Terahertz (THz) or 639,000 Gigahertz (GHz) ... rounded to 3 significant digits since the wavelength is only given to 3 significant digits
Can an object vibrate at the wavelength of light?
No object can vibrate at the wavelength of light. wavelength of light depends on the intensity of light and electron movements.
What is unit of wavelength?
In SI system, unit of wavelength is meter. Any way meter is a large unit so we use Angstrom and some times nanometer. Angstrom (Ǻ) equals to 10 -10 m and nano metre equals to 10-9 m. The range of wavelength for visible light is from 3700 Ǻ to 7200 Ǻ.

What affects light with short wavelength more than light with long wavelength?
Scattering of light
What determine the color of a light wave?
Its wavelength (or frequency).
What is the frequency of a photon whose wavelength is 6000 Armstrong's?
Divide the speed of light (in meters/second) by the wavelength (in meters). The answer is in Hz (1/second). Divide that answer by a million to get MHz.
