What is the velocity of this water wave (give at least two different answers make sure to indicate whether it is moving to the left or right in each case)? y(x) [m] at t= 0.0s +0.1 x (m) 2.0 3.0 1.0 -0.1 y(x) [m] at t 1.0s +0.1 0.0 -0.1 x[m) 3.0 2.0

Answer 1

a) 1) Moving left:

The red point on the wave travels 0.2m to the left in 1s. So the wave travels 0.2 m in 1 second. Now we use

speed = distance/time to get the wave speed.

2) Moving right: The blue point on the wave travels 1.4 m to the right in 1s. So the wave travels 1.4m in 1 second.
