Question

A jump rope is shaken producing a wave with a wavelength of 4 m with the crest of the wave

passing a certain point 5 times per second. What is the velocity of the wave?

A) 20 m/s

B) 1.25 m/s

C) 0.8 m/s

D) 9 m/s

Answer 1

A) 20m/s

Step-by-step explanation:

v= wavelength*frequency

You have a wavelength of 4m and a frequency of 5, so you just multiply 4*5=20 v= 20m/s
