b) frequency of ripple
c) velocity of ripple

As distance between crest and trough is 10 m, the wavelength is 10*2 = 20 m
Frequency = Number of cycles per second or, in this situation, number of full waves per second = 20 Hz
Velocity of ripple = Wavelength * frequency = 20 * 20 = 400 m/s
Frequency = Number of cycles per second or, in this situation, number of full waves per second = 20 Hz
Velocity of ripple = Wavelength * frequency = 20 * 20 = 400 m/s
Yes you are correct. Sorry for the mistake.

so the velocity of the ripple is 4.00 m/s
