Speed of the wave is 4 m/s
Step-by-step explanation:
- Wavelength of the rope is given to be 2 m. It measures the distance between two successive crests or troughs of the wave. Frequency is 2 Hz.
- Speed of the wave is given by
v = f × λ, where f is the frequency and λ is the wavelength.
⇒ v = 2 × 2 = 4 m/s
