What is the wavelength unit of light?
For visible light, the wavelength will usually be specified in nm (nanometers).
Which equipment is most useful when measuring wavelength?
In case of measuring the wavelength of light we use Spectrometer. You could also use an oscilloscope or a dedicated frequency counter.
The unit for measuring the rate at which light energy is rediated from a source is what?
The unit for measuring the rate at which light energy is radiated from a source is the lumen. The lumen is symbolized as lm.
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 unit that astronomers most often use to express the wavelength of light?
Speed of light
How do you work spectrophotometer?
. A spectrophotometer is a photometer (a device for measuring light intensity) that can measure intensity as a function of the color, or more specifically, the wavelength of light
Operation of a simple photometer in measuring light intensity?
unit of photometer
Why spectrophotometer is set in visible range 600nm while measuring bacterial turbidity?
When measuring light scattering it is important to consider the wavelength of light used a bacterial culture. Microorganisms may contain numerous macromolecules that will absorb light, including DNA (254 nm), proteins (280 nm), cytochromes (400-500 nm), and possible cell pigments. When measuring bacteria by light scattering it is best to pick a wavelength where absorption is at a minimum and for most bacterial cultures wavelengths around 600 nm are a good choice. However, the exact wavelength chosen is species specific. It is best to pick a wavelength where absorption is at a minimum.
What is the highest unit for measuring length?
light year * * * * * A parsec, which is approx 3.26 light years, is bigger.
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.
