how do you draw a spectroscope of a star?

Answer 1

Hi. Usually there is a filter consisting of a fine grate of lines. If you mean spectrogram then a photo is taken, enlarged many times, and the spectrum of emission and absorption lines become large enough to see.

Answer 2

You are very confused, and need to do some basic reading in astronomy, telescopes, scientific instruments, and scientific measurements first.

A spectroscope is a type of instrument used for viewing the spectrum of a beam of light through an eyepiece.

If you mean, "how do you draw the spectrum of a star," it is not worth the trouble. Stellar spectra are very complex and can only be recorded usefully by photographic methods.

You could make a representational sketch of a spectrum by drawing two parallel lines across a sheet of paper and then drawing groups of perpendicular lines of varying thicknesses between them. This would give a vague impression of what a spectrogram looks like.

William Wallace Campbell [b. Hancock County, Ohio, April 11, 1862, d. San Francisco, June 14, 1938] discovers from studies with a spectroscope that Polaris (the North Star) is actually a system of three stars.

Solon Irving Bailey [b. 1854, d. 1931] discovers 85 variable stars with short periods in the globular star cluster M5. Such cluster variables, also known as RR Lyra stars after their brightest member, usually have periods of less than a day and are found throughout the Milky Way.

German-American physiologist Jacques Loeb [b. Mayen, Germany, April 7, 1859, d. Hamilton, Bermuda, February 11, 1924] demonstrates parthenogenesis (reproduction without sexual union) by raising unfertilized sea urchin eggs to maturity after changing their environment.

Answer 4

with a prism the light is decomposed and the spectrum is recorded on photographic paper
