What is the wavelength unit of light?
For visible light, the wavelength will usually be specified in nm (nanometers).
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 of EM wave frequency?
Seconds for wavelength, and inverse seconds for frequency also known as hertz. Hz
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 is the wavelength unit of light?
For visible light, the wavelength will usually be specified in nm (nanometers).
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 for measurement of light?
You cannot 'measure' light. However, there is the light-year, a measurement of the distance light can travel in one year. there are many. Lumens, cadlepower, foot candles and candelas. There are probably a few more.
Which unit of measurement uses the distance light travels in one year - 9470000000000km?
The unit of measurement is the "light year".
What is the SI measurement of light?
There is no "measurement of light". The units used depend on what you want to measure: its speed, frequency, wavelength, energy per photon, etc.
The candela is a unit of measurement of what?
A candela is a unit of measurement for light sources and light emissions. Light beams projects different color at different wavelengths, and a candela is used to measure the intensity of the light.
What is the unit that astronomers most often use to express the wavelength of light?
Speed of light
Line with a wavelength of 397 ultraviolet?
The answer depends on the measurement unit used for 397. Since this is unspecified, there can be so sensible answer.
When do you use a light year?
You don't use it, it is a unit of measurement.
When do you use a light-year?
You don't use it, it is a unit of measurement.
What is the unit of measurement of EM wave frequency?
Seconds for wavelength, and inverse seconds for frequency also known as hertz. Hz
Which unit of measurement represents the distance light travels in one year?
light-year
