Answer:
18.8 Hz
Explanation:
The formula relating the frequency (f) and wavelength (λ) is
fλ = v Divide both sides by λ
f = v/λ
Data:
v = 150 m·s⁻¹
λ = 800 cm = 8.00 m
Calculation:
f = 150/8.00
f = 18.8 s⁻¹
f = 18.8 Hz
Answer:
18.75 is the frequency of the wave in hertz.
Explanation:
Velocity of the wave = V = 150 m
Wavelength of the wave = [tex]\lambda [/tex] = 800 cm
[tex]800 cm = 800\times 0.01 m = 8 m[/tex] ( 1 cm = 0.01 m)
Frequency of the wave = [tex]\nu[/tex]
[tex](frequency)\nu=\frac{V(velocity}{\lambda (wavelength)}[/tex]
[tex]\nu=\frac{150 m/s}{8 m}=18.75 s^{-1}=18.75 Hz[/tex]
18.75 is the frequency of the wave in hertz.
