Velocity, v, frequency, f, and wavelength, λ, relationship:
Frequency, f = 0.55 kHz (1000Hz/1kHz) = 550 Hz
A student standing in a canyon yells "echo", and her voice produces a sound wave of the frequency of f = 0.55 kHz. The echo takes t = 4.5 s to return to the student. Assume the speed of sound through the atmosphere at this location is v=324 m/s.
f = 0.55 kHz
t = 4.5 s
v = 324 m/s
What is the wavelength of the sound wave in meters?
