Velocity=frequency×wavelength=500× (1/500×0.02)×20=20/0.02=1000m/s , how to find length,for 0.02sec---20m and for T=1/f=1/500------? ?=1/(500×0.02) ×20m= wavelength

 Here , Velocity = distance covered / time taken
 c=20/0.02=1000ms-1 . So , wave velocity is 1000ms-1 . This can be bone in other way too by converting the Hz value
