What is the unit astronomers most often use to express the wavelength of light called?
LooneyTunerIan
The wavelength of light is expressed in different metric subunits derived from meters. For example, radio waves are measured in meters, visible light is measured in nanometers, and gamma rays are measured in picometers.
I believe that would be the nanometer. In the past, the angstrom (= 1/10 nm) has been frequently used.

What is the unit that astronomers most often use to express the wavelength of light?
Speed of light
What is the unit that astronomers most often use to express the wavelength of light is called?
For visible light, the nanometer (nm) is usually used. For other wavelengths of EM waves, other prefixes can be used with the meter; for example meter, kilometer, millimeter, femtometer, etc.
What is a wavelength of light that can be seen called?
It is literally called visible light..
How can astronomers determine whether a star is moving towards or away from earth?
Astronomers determine whether a star is moving toward or away from the Earth via the Doppler effect. Imagine a motorcycle moving past you. As it drives towards you, it has a higher frequency, and a lower frequency when it drives away. The same thing happens with light. As an object moves towards us, its light has a higher frequency and lower wavelength - this is called blueshift. As an object moves away from us, its light has a lower frequency and higher wavelength - this is called redshift.

What is a light having one wavelength called?
At a single wavelength, it is called monochromatic
How do scientists determine the chemical makeup of the stars?
Different chemicals emit and absorb light at various wavelengths. Astronomers can look at the wavelength of light coming from stars and determine which chemicals must be present.
What is the number of centimeters between waves of light?
The measure of a light's frequency is called wavelength.
What is longer than visible wavelength called?
Infrared has a longer wavelength, and a lower frequency, than visible light.
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 the shift in the light of a galaxy toward the red wavelength called?
This phenomenon is called red shift.
What has a visible wavelength?
Light with wavelengths between 3500 and 6500 angstroms: called the visible light spectrum.
