A jump rope is shaken producing a wave with a wavelength of 0.5m with the crest of the wave passing a certain point 4 times per second. What is the velocity of the wave?



Answer :

The wave equation states that v=f*lambda in this case f=4 and lambda=0.5m
Therefore we can multiply 4 and 0.5 to find the velocity of the wave to be 2m/s
