Heya!!
For calculate speed of the wave, lets applicate formula:
[tex]\boxed{v=f* \lambda}[/tex]
Δ Being Δ
f = Frequency = 50 Hz
v = Velocity = ?
[tex]\lambda[/tex] = Wavelenght = 10 m
⇒ Let's replace according the formula:
[tex]\boxed{v = 50\ Hz * 10\ m }[/tex]
⇒ Resolving
[tex]\boxed{v= 500\ m/s}[/tex]
Result:
The speed of that wave is 500 meters per second.
Good Luck!!
