Fourier Series and Absorbtion questions?

  • #1
I have to do a science fair, and I am really interested in physics. I spent forever trying to think of a topic, and I got myself stuck doing something with waves. After weeks of thinking of an expirement that will compete well without being extremely difficult, I came up with one.

Does using the Fourier Series effect a wave's ability to penetrate objects?

I know that has to be worded differently.

But my questions are,

- Can you use the fourier series on light waves, or just sound?
-If I test this with light waves, I have easy access to a spectrometer and other instruments needed.

I was planning on comparing the spectrometer results with the original light and the light going through the material, but I don't know if that would provide accurate results.

-If I work with sound waves, I know the Fourier Series can be easily done, but can I measure the absorbtion of the material?

I know this is all over the place, I just really need guidance. Thank you so much
