Explanation:
To find the wave speed of a wave you can use this formula :
wavespeed (v) = (frequency) x (wavelength λ)
Plug in our values :
v = (10Hz) x (2m)
v = 20 m/s
Hope this helps!
Now, seriously !
There's a stream of objects flowing past you.
Ten of them pass you every second.
Each one is 2m long.
Don't you think you can figure out how fast they're flowing ?
