Balanced chemical equation for above reaction :

This is a displacement reaction, where copper (Cu) being morereactive than Silver (Ag) displaces Silver from its compound " Silver Nitrate " to form " Copper Nitrate " and silver .

If the wavelength of the wave is increased to 10 m, the frequency of the wave will be 60 Hz
<h3>Data obtained from the question </h3>
- Wavelength (λ) = 10 m
- Velocity (v) = 600 m/s
<h3>How to determine the frequency of the wave </h3>
The frequency, wavelength and velocity of a wave are related according to the following equation:
Frequency (f) = velocity (v) / wavelength (λ)
f = v / λ
With the above formula, we can obtain the frequency of the wave as follow
f = v / λ
f = 600 / 10
f = 60 Hz
