One of the uses for spectroscopy is to identify properties about space objects: chiefly their temperature, as well as their velocity From this understanding a scientist analyses the spectrum from a star by using spectroscopy, they will see either dark or bright bands in certain locations. This means that certain wavelengths of light are being absorbed or emitted by the star. In this way, the scientist can discover which elements are present in the star. They compare the line spectra of elements to that of the star, and when there are corresponding bright lines, that element is present in the stars.
What is the other feature that a spectrometer can be used for star and galaxy spectrum analysis?
Is there other area where a spectrometer can be utilized?
A sphere of radius R is uniformly charged to a total charge of Q. It is made to spin about an axis that passes through its center with an angular speed ω. Find the magnitude of the resulting magnetic field at the center of the sphere.
A resistor is in the shape of a cube, with each side of resistance R . Find the equivalent resistance between any two of its adjacent corners.
