Answer:
where are the statements so i can see which one is correct
Explanation:
Answer:
Amplitude.
Explanation:
The velocity of a wave is given by :
velocity = total distance covered/total time taken
In the case of a wave the total distance covered is equal to the amplitude of a wave. It is the maximum displacement covered by the wave. So, the velocity of a wave is a function of its amplitude. Hence, the correct option is (D).
