Do you have an ideas for what to use to hold the CD in place?

The third spectroscope they sugggested is just positioning a CD to where the spectrum is visible on it. Could i just draw the scale onto the CD?
Thanks.

Okay that all sounds great.
One thing though.. Is there a way with the other two spectroscopes on the Arbor Science site to project them onto a piece of paper?
Thanks.

Thanks. The scale idea makes a lot more sense now as this solved many questions I had. From the list of LEDs you sent me, would it be best to get the most intense red and least intense blue to create a wider scale? If so, which ones would this be? Lastly, how will i project the spectrum readings ont...

Thanks for the advice. I understood everything you said except for the part about dividing the line into equal segments..
How would this be useful to me?

Thanks.

Thanks for the advice on the light sources. Are all of these LEDs available at a local hardware store? Also, by using the LEDs would i be elimeinating the oter ligth sources from my experiment? How could I mark the center of the two readings on my display, and how would I create the scale to make th...

Yes it seems you are interpreting mw experiment plan correctly. However, I am a little confused about what your saying as to the three things to focus on with my measurement. See, all the research sources i've used fail to give me a direct answer. Once I am looking into the spectroscope, and i see t...

Thanks Craig.. I understand what your saying about my question. My original question was "What are the effects of different light sources on wavelenght spectroscopy?" However, my teacher reccomended I do a more hands on project. It is similar to the ideas on this site : http://www.arborsci...

My research question is: "What is the effect of different light sources on wavelength spectroscopy measured with homemade and commercial spectroscopes?" However, i'm not quite sure how i can measure this. I've been reading about how to read the lines of the spectrum but am confused by it. ...

I am working on a science fair project about yeast fermentation in different liquids. I have done plenty of research and am working on my Experiment Plan. I was just wondering if you knew of any good sites to use. Also, what kind of yeast should i use for my experiment? Lastly, i am measuring the mo...
