The diagram below shows a model of four waves. Which wave has the shortest wave length? A, B, C, D

Answer : The wave A has the shortest wave length.
Explanation :
As we know that there is an inverse relationship between the wavelength and the frequency.
[tex]\nu \propto \frac{1}{\lambda}[/tex]
From this we conclude that the higher the frequency, lower will be the wavelength of the wave and vice-versa.
From the given waves, wave A has the shortest wavelength and wave D has the longest wavelength.
Hence, the wave A has the shortest wave length.
