(12%) Problem 8: A student standing in a canyon yells "echo", and her voice produces a sound wave of frequency of f= 0.61 kHz. The echo takes 1 = 2.1 s to return to the student. Assume the speed of sound through the atmosphere at this location is v= 320 m/s. Randomized Variables f=0.61 kHz t = 2.1 s ym 320 m/s 33% Part (a) What is the wavelength of the sound wave in meters? λ= sin() cotan() atan() cosh() cos() asin() acotan() tanh()) Degrees O Radians tan() acos() sinh() cotanh() Submit Hint ( ET 7 8 9 HOMET 4 5 6 3 7* 1 2 0 VO BACKSACK + + Foodback I give up!
