Wavelength is 0.403m and it travels 500m in 20 seconds.
Explanation:
In this case we can use the equation:
Where v is the velocity of the wave in meters per second, f is the frequency in hertz and
Hence for (a):
25=62
For (b)
Speed=(distance)/(time)
Multiply both sides by 20 to cancel the fraction.
