Imagine the bird is sitting on the post in the water. If the portion of the wave bewteen 2 crests passes the post every scond what is the speed of the wave ?
To find the speed of the wave, we need to know the distance between the crests and the time it takes for the wave to pass the post.
In this case, we are given that the portion of the wave between two crests passes the post every second. So the time it takes for the wave to pass the post is 1 second.
However, we don't have the distance between the crests. Without this information, we cannot directly calculate the speed of the wave.
The speed of a wave is calculated by dividing the distance traveled by the time it takes to travel that distance. In this scenario, we only have the time and not the distance.
Hence, without the distance between the crests, it is not possible to determine the speed of the wave in this specific scenario.
