Answer:
The frequency of a wave is 35 Hz.
Explanation:
Speed of a wave is 140 m/s
Wavelength of a wave is 4 m
It is required to find the frequency. The relation between frequency, speed and the wavelength of a wave is given by :
[tex]v=f\lambda[/tex]
f is frequency
[tex]f=\dfrac{v}{\lambda}\\\\f=\dfrac{140\ m/s}{4\ m}\\\\f=35\ Hz[/tex]
So, the frequency of a wave is 35 Hz.
The frequency of a wave will be "35 Hz".
Wavelength and Frequency
The distance between one point on something like a wave and the similar position somewhat on the following wave is measured in wavelengths. This same sequence of waves that travel through some kind of spot together in seconds is defined as the frequency.
According to the question,
Speed of wave, v = 140 m/s
Wavelength, λ = 4.0 m
We know the relation,
→ Speed (v) = Frequency (f) × Wavelength (λ)
or,
→ f = [tex]\frac{v}{\lambda}[/tex]
By substituting the values,
= [tex]\frac{140}{4}[/tex]
= 35 Hz
Thus the response above is answer.
