waves in a lake are observed to be 5 cm in length and to pass an anchored boat .8 s apart. the speed of the wave is

To find the speed of the wave, we need to use the formula:

Speed = Distance/Time

In this case, the distance is the length of the wave, and the time is the time taken for the wave to pass.

Given:
Length of the wave = 5 cm
Time between waves = 0.8 s

To find the distance traveled by the wave, we need to convert the length of the wave from centimeters to meters:

Distance = 5 cm = 0.05 meters (since 1 meter = 100 cm)

Now, let's use the formula to find the speed:

Speed = Distance/Time = 0.05 meters / 0.8 seconds = 0.0625 m/s

Therefore, the speed of the wave is 0.0625 m/s.
