Correct Answer: Option D
Explanation

distance between two successive crests of a water wave = \(\lambda\) = 0.25m

 Frequency (f) is defined as the number of cycles or oscillations that occur in one second = four complete vertical oscillations in one second = 4Hz

Speed of wave (v) = f x \(\lambda\) = 0.25 x 4 = 1m/s

 

There is an explanation video available below.
