A student attaches a *f* = 3.5 kHz oscillator to one end of a metal rail of length *L* = 19 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* = 0.0062 s to travel the length of the rail.

What is the speed of the wave in the rail, in meters per second?

Step 1

**Given information:**

The length of the rail (l) = 19 m

Time taken to by so...
