10 ocean water waves whose crests are 12 meters apart reach or hit the shore each minute. What is the wavelength, wave frequency, and wave speed?

#v = 2 m/s#

Explanation:

The wavelength, #lambda# is 12 m. That is given.

Frequency, #f#, is easily obtained from the info.

#f = ("10 cycles")/(60 "seconds") = 0.167 "cycles"/s = 0.167 Hz#

For wave speed, #v#, use the formula

#v = lambda*f#
#v = 12 m*0.167 Hz = 2 m*"cycles"/s = 2 m/s#

(Cycles is not a unit, it is merely a visualization aid.)

I hope this helps,
