What is the formula to calculate wave speed?
Remember the role of gravity and depth.
How deep is the stream where the trout jumps in the example?
It's given in the problem.
What is the speed of a wave in a 0.8 meter deep stream?
Use the depth of the stream in the formula.
True or False: The flow velocity must always be lower for waves to stay in place.
Think about the interaction of wave speed and flow.
In a river where the water is 1 meter deep, calculate the wave speed and discuss why maintaining this speed is essential for aquatic life.
Refer back to the wave speed formula for your calculations.
A stream's flow velocity is 4 m/s. If the depth is 0.6 m, will the waves travel upstream or remain stationary? Justify your answer using relevant calculations.
Compare the calculated wave speed against the flow velocity.
