_______
=10.2 Hz m/s(31)m/s(39)m/s(140)m/s

Answer:

Speed, v = 140 m/s      

Explanation:

It is given that,

Wavelength, λ = 35 meters

Frequency of the wave, υ = 4 Hz

The speed of the wave is the product of the frequency and the wavelength of the wave.

Mathematically, it can be written as :

v = υ λ

v = 35 m × 4 Hz

v = 140 m/s

So, the speed of the wave is 140 m/s

Hence, this is the required solution.
