The frequency of the wave is 4 Hz
Explanation:
The relationship between wave, frequency and speed of a wave is given by the equation:
[tex]v=f \lambda[/tex]
where
v is the speed of the wave
f is the frequency
[tex]\lambda[/tex] is the wavelength
For the wave in this problem, we have:
[tex]v=60 cm/s[/tex] is the speed
[tex]\lambda=15 cm[/tex] is the wavelength
Solving the equation for f, we find its frequency:
[tex]f=\frac{v}{\lambda}=\frac{60 cm/s}{15 s}=4 s^{-1} = 4 Hz[/tex]
