Question

If 20 waves are pass through a point in 4s and distance between crest and adjacent through is 0.05m then velocity of the wave is

Answer 1

Answer:

given data

                     n = 20 waves           t = 4 s       wave lenght = 0.05 m

solution

                     V = frequency * wave lenght

                     V = n/t * 0.05 = 20/4 * 0.05 = 0.25 m/s
