Hello,
I am researching sound at Concordia University, Quebec. Recently, my mind was wondering and I thought about sound being produced by the air molecules bumping into each other. I began to wonder what else could do the same thing.
Does light have contact with the air molecules in this same way?
Or does a "laser"?
There is this tool guitarists use called a an "ebow" which is a sort of "lazer" that is placed over the string and ends up vibrating the string. This is the sort of thing I would like to understand better?
Thanks
Jay
