frequency=velocity/wavelength
=65/0.8=325/4=81.25/sec
=81.25 Hz

frequency = velocity/wavelength for *any* wave. So
65/.8 = 81.25 Hz.

speed= frequency X wavelength
frequency= speed / wavelength
= 65/0.8
=81.25(ans)

velocity = wavelength*freq
so 65 = 0.8*freq
freq=81.25Hz

81.25 Hz
Frequency = velocity / wavelength
65/.8 = 81.25
