Answer:
The frequency of wave is 4.34 Hz.
Explanation:
We know the relation:
λ = [tex]\frac{v}{f}[/tex] = [tex]v[/tex] × [tex]T[/tex]........................................1
where,
λ= wavelength
v= velocity of wave
T= Period of wave
By the definition of period T, you are given that HALF of T is 0.115 s, so
T = 2 × (0.115 s)
= 0.23 s
Then ,
λ = v × T
= (7.33 m/s) × (0.23 s)
≅ 1.686 m
Now for frequency, return to equation 1,
[tex]f[/tex] = [tex]\frac{v}{ \lambda }[/tex]
= [tex]\frac{7.33}{1.686}[/tex]
= 4.34
The frequency of the wave is calculated as 4.34 Hz.
