Answer:
c. 2 m/s
Explanation:
The relationship between speed, frequency and wavelength of a wave is given by:
[tex]v=f \lambda[/tex]
where
v is the speed of the wave
f is its frequency
[tex]\lambda[/tex] is the wavelength
For the transverse wave in this problem, we have:
[tex]f = 4 Hz[/tex] is the frequency
[tex]\lambda=0.5 m[/tex] is the wavelength
Substituting these numbers into the equation, we find the speed of the wave:
[tex]v=(4 Hz)(0.5 m)=2 m/s[/tex]
