Answer:
Frequency = Velocity / Wavelength = 100 m/s / 20 m = 5 s-1 or 5 Hz.
Explanation:
The frequency of a wave with a velocity of 100 m/s and a wavelength of 20m is 5 Hz.
So, option A is correct one.
What is frequency?
- The number of waves that pass per unit time is called frequency.
- Formula: [tex]v = c/lamda[/tex]
v = Frequency of wave
c = Velocity
lamda = wavelength of wave
Calculation,
Let velocity = 100 m/s
wavelength = 20m is 5 Hz.
Then, Formula: [tex]v = c/lamda[/tex]
[tex]v[/tex] = 100 m/s / 20m = 5 [tex]s^{-1}[/tex] = 5 Hz ( 1 [tex]s^{-1}[/tex] = Hz )
So, frequency of wave is 5 Hz
