(4%) Problem 14: A student standing in a canyon yells "echo", and her voice produces a sound wave of frequency of f= 0.59 kHz. The echo takes t = 3.5 s to return to the student. Assume the speed of sound through the atmosphere at this location is v = 332 m/s. Randomized Variables f=0.59 kHz t = 3.5 s v = 332 m/s 33% Part (a) What is the wavelength of the sound wave in meters? = 562.71 sin() cos() cotan() asin() atan() acotan() cosh() tan() J ( acos() E ^^^ sinh() tanh() cotanh() Degrees Radians Hints: 0% deduction per hint.
