Question

A 2280-Hz sound wave has a wavelength of 0.655 m in an unknown medium. What is the speed of the wave?

Answer 1

Wave speed = (frequency) x (wavelength)

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

= 1,493.4 meter per second

Answer 2

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
