1) A student standing in a canyon yells "echo", and her voice produces a sound wave of frequency of f = 0.65 kHz. The echo takes t = 3.9 s to return to the student. Assume the speed of sound through the atmosphere at this location is v = 325 m/s. a) What is the wavelength of the sound wave in meters?  b) Input an expression for the distance, d, the canyon wall is from the student.  c) How many wavelengths are between the student and the wall?
