I did an experiment for school, and I put a speaker in a styrofoam box with a rectangle cut out of the front. I had styrofoam bricks that fit perfectly in the hole, each with a hole cut out. The hole shape differed, with things like a funnel, a diagonal line, a circle, a square, etc. I was...
Sorry for the wording of the topic- I couldn't figure out how to make it fit.
If I passed a hypothetical square wave through a material- be it wood, glass, cotton, etc.- would it change to look more like a sine wave?
Sorry if I am posting in the wrong place.
I'm really interested in the Fourier series, but I'm not an expert on it yet. I am very well aware yoy can do it with sound waves, but can you manipulate any other waves? What about light waves?
And for absorption, how can you measure the...
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...
