Answer 2

Calculation of Wave Speed

To determine the wave speed, we can use the formula:

Wave Speed = Distance / Time

In this case, the given distance between neighboring wave crests is 12 m, and the time it takes for 18 wave crests to pass by is 1 minute.

Plugging these values into the formula, we get:

Wave Speed = 12 m / 1 min

However, we need to convert the time from minutes to seconds, as the SI unit for time is seconds. There are 60 seconds in 1 minute, so we can multiply the time by 60 to convert it to seconds.

Wave Speed = 12 m / (1 min * 60 s/min)

Simplifying the expression, we have:

Wave Speed = 12 m / 60 s

Finally, calculating the wave speed:

Wave Speed = 0.2 m/s

Therefore, the speed of the waves is 0.2 m/s.
