Speed , v = fλ

where v is speed in m/s, f = frequency in Hz, and λ is wavelength in m

v = 2880 Hz * 0.655m

v = 1886.4 m/s

Speed of the wave is = 1886.4 m/s

Wave speed  =  (frequency) x (wavelength)

                       =  (2,280 per second) x (0.655 meter)

                       =          1,493.4 meter per second
