the distance between two wave crests in the water is 3 meters. a swimmer notices one wave goes by every 6 seconds. What is the spped of the waves
distance = speed * time
3 = v * 6
v = 1/2 meter /second
note - that is called the "phase speed" and is the observed speed of a wave crest. It is not the speed of the propogation of the wave system called "group velocity".
To determine the speed of the waves, you need to divide the distance traveled by the time it takes. In this case, the distance between two wave crests is given as 3 meters, and the time it takes for one wave to pass by is 6 seconds.
Speed = Distance / Time
Speed = 3 meters / 6 seconds
Speed = 0.5 meters per second
Therefore, the speed of the waves is 0.5 meters per second.
To calculate the speed of the waves, we need to use the formula:
Speed = Distance / Time
In this case, the distance between two wave crests is given as 3 meters, and the time it takes for one wave to go by is given as 6 seconds.
Substituting the values into the formula, we get:
Speed = 3 meters / 6 seconds
Simplifying the expression:
Speed = 0.5 meters per second
Therefore, the speed of the waves is 0.5 meters per second.
