Answer:
The wavelength of the wave is tripled this can be done by reducing the frequency of the wave by factor of three.
Explanation :
The relation between the wavelength & frequency of a wave is given by
C = ν λ
Where
C - it is the velocity of light in vacuum.
ν - frequency of the wave.
λ - wavelength of the wave.
So we find that wavelength of a wave varies inversely with the frequency of a wave i.e. ν ∝ 1/λ.
