Heya!!
For calculate frequency, lets applicate formula:
[tex]\boxed{f=v/\lambda}[/tex]
Δ Being Δ
f = Frequency = ?
v = Velocity = 144 m/s
[tex]\lambda[/tex] = Wavelenght = 0,5 m
⇒ Let's replace according the formula:
[tex]\boxed{f = 144\ m/s / 0,5\ m }[/tex]
⇒ Resolving
[tex]\boxed{f = 288\ Hz}[/tex]
Result:
The frequency of that wave is 288 Hertz
Good Luck!!
