Explanation:
f = c / λ = wave speed c (m/s) / wavelength λ (m). The formula for time is: T (period) = 1 / f (frequency). λ = c / f = wave speed c (m/s) / frequency f (Hz). The unit hertz (Hz) was once called cps = cycles per second.

Answer:
0.46 m/sec
Explanation:
Wavelength = 4.6 metres
Time period = 10 seconds
Frequency = 1/time period = 1/10 Hertz
Velocity = Wavelength × Frequency
Velocity = 4.6×1/10 = 0.46 m/sec
Therefore the velocity is 0.46 m/sec.
