The image shows a wave diagram with the following information: - The wave travels a distance of 20 cm. - The time period is 12 seconds. Calculate the wave velocity in m/s.

To find the wave velocity, we can use the formula for wave velocity, which is:
v = T d ​
where:

v is the wave velocity in meters per second (m/s),
d is the distance that the wave travels in meters (m),
T is the time period in seconds (s).

In the given problem:

The wave travels a distance of 20 cm. First, we need to convert this distance to meters by dividing by 100, because there are 100 centimeters in a meter.
d = 20 cm = 100 20 ​ m = 0.2 m

The time period T is given as 12 seconds.


Now we can substitute these values into the formula:
v = 12 s 0.2 m ​ ≈ 0.0167 m/s
Thus, the wave velocity is approximately 0.0167 meters per second.
