(30 points)Follow the instructions to construct a spectrometer and answer the corresponding questions.The instructions below describe how to build a spectroscope. Here is a link to the site where the instructions are taken from: What you will need:Our spectroscope has three main parts: there is a slit made from two razor blades; a diffraction grating made from a CD; and a viewing port made from a paper tube.To make sure that all three parts are lined up properly, we will use the CD as a measuring device, and mark the spots where the slit and the viewing port will go.Once you have assembled your spectrometer using the instructions in the lecture and above, use it to examine the spectra of three different light sources. Make sure that at least one of them is the sun or moon, but the others can be, for example, incandescent lights, compact fluorescent bulbs, LED lights, halogen or xenon bulbs, televisions, computer screens, candles, or fireplaces.Answer the following questions:For this, you will need an empty toilet paper roll and a clear, dark night. Before you start, jot down the number of stars that you think you can see in the night sky.Aim your toilet paper roll at a part of the sky well above the horizon to avoid any haze pollution. Hold your roll steady, and allow your eyes to get used to the light for a few seconds.Count the number of stars that you can see through the roll. Do this four more times in other parts of the sky, and average the five counts.The viewing diameter of a toilet paper roll is about 1/135th of the entire sky, at least for a relatively flat area. Mountains, buildings, or large trees will obscure some of the sky. To determine the number of visible stars, multiply your average by 135.Answer the following questions:Answer the following questions:Submit a lab report file (Microsoft Word or Excel is preferred) including answers to the eight questions in this exercise. Your paper should conform to . It is strongly recommended that you submit all assignments to the TurnItIn Originality Check prior to delivering them to your instructor for grading. If you are uncertain how to submit an assignment to TurnItIn, review the TurnItIn Originality Check – Student Guide for step-by-step instructions.
