Speed of standing wave
1. The problem statement, all variables and given/known data
The standing wave in the picture is oscillating at 100 Hz. What is it's velocity?
2. Relevant equations
I believe is the equation that applies here.
3. The attempt at a solution
The wavelength from the picture appears to be 20x10-2 meters.
So velocity should equal (20x10-2)(100)= 20 meters per second
But I know this answer is wrong. Where am I going wrong?

Also, be careful with your units. It looks like you are mixing cm and meters in your multiplication and answer....?
