Scientists determined this was expanding by using the spectrograph?
Scientists determined that the object was expanding by analyzing its light spectrum using a spectrograph. By observing the Doppler shift in the spectral lines, scientists could infer the motion of the object relative to Earth, leading to the conclusion that it was moving away and expanding.
What is the emission spectrograph used for?
An emission spectrograph is used to identify elements present in a sample by measuring the wavelengths of light emitted when the sample is excited. It can be useful in various fields such as chemistry, environmental science, and material science for identifying unknown substances and analyzing their composition.
What is a device that separates the light from stars and other objects according to wavelength in order to produce a spectrum?
A spectrograph is a device that separates light from stars and other objects into its different wavelengths to produce a spectrum. This allows astronomers to study the composition, temperature, and other properties of the object emitting the light through analysis of the spectrum.
What is the difference between Aston's mass spectrograph and Dempster's mass spectrometer?
Aston's mass spectrograph is a magnetic sector mass spectrometer that separates ions based on their mass-to-charge ratio using magnetic and electric fields. Dempster's mass spectrometer is an early design of a mass spectrometer that used electric and magnetic fields to separate ions based on their mass-to-charge ratio. Aston's design was an improvement over Dempster's, offering higher resolution and precision in analyzing isotopic composition.
What r d differences between spectrometer and spectrograph?
spectrometer is a device that gives the spectrum of all intensities of a one wavelength at one time. it consists of the entrance & exit slits, dispersing element (like grating) &mirror. it detects the light and measure the intensities with a photomultiplier tube or other detectors and data acquisition system. spectrograph also gives the spectrum of all intensities of a wavelength at one time.it consists of the entrance & exit slits, dispersing element (like grating) &mirror but it does not have any detector and does not record the spectrum.
Is an instrument used by astronomers to study heavenly bodies and is used to determine the composition of the heavenly bodies through their color patterns?
Spectrograph.
How does a spectrograph provide information about stars chemical composition?
A spectrograph breaks down the light from stars into its component colors or wavelengths. Each chemical element absorbs and emits light at specific wavelengths, creating a unique fingerprint called a spectral line. By analyzing the spectral lines in a star's light, scientists can determine its chemical composition.
What instrument do the astronomers use to determine the chemical composition of a star?
They use a spectrograph to pass light through a prism to break it the light waves into its constituent colors. Then by looking at what colors are missing they can determine both the temperature and composition of the star.
Why do scientists use a spectrograph?
because they want to
What is a calutron?
An electromagnetic apparatus for separating isotopes of uranium and other elements according to their masses, using the principle of the mass spectrograph. It lost me at 'mass spectrograph'.
An istrument that breaks the light from an object into colors?
A spectrograph can do that.
What is a carbon arc emission spectrograph?
A carbon arc emission spectrograph is a piece of scientific equipment. Emission spectography is used to measure radiation intensity, and provides information about atoms and molecules as well as chemical composition of objects.
What is the detector in a spectrograph in which spectral lines are recorded photographically?
The detector in a spectrograph that records spectral lines photographically is a photographic plate or film. This photographic medium captures the light from the spectral lines dispersed by the spectrograph, allowing them to be recorded for analysis and interpretation.
Can a spectrograph tell the age of a star?
Yes, but not to any precision.
What do spectrograph do?
A spectroscope identifies the elements by the color that they give off.
What are the evidences for Helium and Hydrogen in sun?
Scientists can determine the contents of stars using spectrometer (spectrograph or spectroscope.) Basically different compounds give off different wavelengths of of light. By measuring the light you can identify the compound.
How is a chromatic aberration related to a prism spectrograph?
chromatic aberration is due to the change in n, which is a function of the wavelength. different wavelength--> different n--> different refraction-->different angle-->this is spectrograph.
