(8%) Problem 6: A student attaches a f= 3.5 kHz oscillator to one end of a metal rail of length L = 25 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= 0.0076 s to travel the length of the rail. ▷ A 25% Part (a) Input an expression for the period of the waves in the rail, in terms of the given quantities.
