For example, if you choose to participate in write-on, you will be partially judged on the accuracy of your Bluebooking. Similarly, Bluebooking can provide anybody reviewing a writing sample an easy way to make a âfirst cutâ and divide applications between those that will get a closer look and those that will not.
A spectrum analyzer is a device used to examine the spectral composition of some electrical, acoustic, or optical waveform. Often, it measures the power spectrum.
Taking this up to a level higher, you can break down a starâs spectrum and analyze it using a spectrograph. The spectrograph is the name for the instrument used in analyzing a starâs spectrum. There are two common ways by which a spectrograph splits a starâs light into its spectrum; via refraction and diffraction. Refraction is done through a prism and this is similar to the process by which a rainbow is formed.
