Answer: 3 m/s
Explanation:
The wavespeed of a wave is the distance covered by the wave in one second. It is measured in metre per second, and represented by the symbol V.
Wavespeed (V) = Frequency F x wavelength λ
V = F λ
In this case,
wavelength (λ)= 1 m
Frequency = 3 Hz.
Hence, V = F λ
V = 1m x 3Hz
V = 3 m/s
Thus, the wavespeed is 3m/s
