You’re welcome. Having the double axis diffraction grating explains why you are seeing multiple images of the ruler. That diffraction grating won’t work for this experiment because it is essentially splitting the light ing two different directions. So, you will indeed need to get a linear diffraction grating such as the one recommended on this page.
Thank you for your reply. We have the same brand, but our diffraction grating is the 13,500 double axis diffraction grating. Can we make that work? Or, will we need to order the one you suggested? We will play with the width of the space between razor blades, also.
If you’re seeing multiple images of the ruler, this usually has to do with the diffraction grating you are using. I just updated the link for the diffraction grating. This link provides one that has 500 lines. Do you know how many lines your diffraction grating has?
To make the colors as visible as possible, try moving one of the razor blades to make the slit smaller or wider.
We made the spectrometer just like you said, but, the ruler looks really fuzzy and is very difficult to read. It splits up into 3 rulers like when you put your eyes out of focus. you can see some colors, but, it is so difficult to read and so split that we don’t know what we are looking at and we certainly can’t see the measurements to read anything. Any suggestions?
Yes, that’s perfect. Just be sure to calibrate precisely and it will work well for you.
Can this work with a double-axis diffraction grating? Are any changes in the construction needed?
