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.
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 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'.
Why does a spectrograph do?
A spectrograph is an instrument that separates incoming light into its component wavelengths, producing a spectrum that can be analyzed for various properties. It captures the intensity of light at different wavelengths, allowing scientists to study the composition, temperature, density, and motion of astronomical objects or chemical substances. By examining the spectrum, researchers can identify specific elements and compounds, as well as gain insights into physical conditions and processes.
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.
An istrument that breaks the light from an object into colors?
A spectrograph can do that.
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.
Do scientists use algebra?
yes.Yup. Scientists use algebra all the time, no question. Even biologists.
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 do scientists use to measure earthquakes?
Scientists use seismographs.
How do scientists know what the sun is made of?
Scientists know what the sun is made of by studying its spectrum. By analyzing the light emitted by the sun, they can identify the different elements present in its atmosphere based on the unique patterns of absorption and emission lines. This approach allows scientists to determine that the sun is mainly composed of hydrogen and helium, with trace amounts of other elements.
