Hi i have a problem.
My physics teacher tells us that a longitudinal wave moving on a spring has speed v=(kL/u)^2 where k is spring constant n L e length of spring u=m/L of that spring..
which i think its unbelievable but the teacher told me its true..
I think the speed of e wave got nothing to do with spring's length.. Which this equation indicates that if u just use a spring 2 times longer, the speed of the wave will be 2 times faster.. which is unbelievable..
Am I wrong or what?
Thank you for all ur help!
