- Frequency ( f ) : The number of complete waves , set up in a medium in one second is called frequency of the wave. The SI unit of frequency is Hertz ( Hz ). For example : if a sound wave completes 15 compressions and 15 rarefactions in one second , it's frequency is 15 Hz.
- Wavelength ( λ ) : The distance between two consecutive troughs or crests in a transverse wave or the distance between two consecutive compressions or rarefactions in a longitudinal wave us called wavelength. It is the distance travelled by a wave in a time equal to it's time period. It's SI unit is metre ( m ).
- Wave velocity ( v ) : The velocity with which a wave propagates in a medium is called wave velocity. It's SI unit is m/s.

Answer:
the resultant velocity is Zero
Explanation:
by the rule of adding and subtracting factors, we know that; when the force acting on an object is from east & north we add and with forces acting from South & west we minus.
Therefore:
1) List the forces down:
the 100m/s acting west is (-) while
the other 100m/s is acting in easterly direction
so it is (+)
2) Add the forces:
-100+100=0
therefore the answer is 0m/s for the the resultant velocity
hope I'm right
