Acertain wave has a wavelength of 35 meters and a frequency of 4.0 hz. what is the speed of the wave? 8.8 m/s 31 m/s 39 m/s 140 m/s

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.

the plateau is likely to turn into a desert do to corrosion.

c)as speed changes, wavelength and frequency change.

everything changes!
