Question

The distance between crest and trough of a wave is 30m/s . What is it's velocity if the wave makes 100 vibrations in 100 sec?


Fasssssssttttttttttttttt​

Answer 1

Answer:

answer is 30 cm/s

hope you understand with mu drawing

Answer 2

Answer:

answer: 30m/s

Explanation:

DATA

waveleigth = 30m

frequency = 100/100s = 1/s

velocity of a wave = wavelength x frequency

velocity of a wave = 30m x 1/s = 30m/s
