(16%) Problem 6: A student attaches a f= 2.5 kHz oscillator to one end of a metal rail of length L = 18 m. The student turns on the oscillator and uses a piezoelectric gauge at the other end to measure that the resulting sound wave takes t= 0.0064 s to travel the length of the rail. &25% Part (a) Input an expression for the period of the waves in the rail, in terms of the given quantities.
