Two successive crests of an approaching water wave are separated by a distance of 1.5m. It takes 0.2s for one crest to cover the distance of 1.5m

1 answer

The speed of the approaching water wave can be calculated as follows:

Speed = Distance/Time

Speed = 1.5m/0.2s

Speed = 7.5 m/s

Therefore, the speed of the approaching water wave is 7.5 m/s.
