Answer:
v = 0.25 m/s
Explanation:
Given that,
The wavelength of a wave, [tex]\lambda=0.02\ m[/tex]
Time period of the wave, [tex]T=8\times 10^{-2}\ s[/tex]
We need to find the speed of a wave. The speed of wave is given by :
[tex]v=\dfrac{\lambda}{T}\\\\v=\dfrac{0.02}{8\times 10^{-2}}\\\\v=0.25\ m/s[/tex]
So, the speed of the wave is 0.25 m/s.
