As the speed and length of a wave decreases, the wave _____.

grows shorter

grows higher

moves backwards

moved in a circle


Verified Answer :

The answer is {B. Grows higher}

The  speed of a wave measures how far one particular crest (or trough) moves in a given amount of time. The speed of the wave changes according to the following equation:


v  =  λ

  • f

    According this equation, it follows that as the speed and length of a wave decreases, the wave grows higher (the higher the frequency).
