Answer:
Amplitude of wave is changing
Explanation:
As we know that amplitude is defined as the displacement of medium particle about its mean position.
This amplitude also help to evaluate the energy of wave. It is given by
[tex]E = kA^2[/tex]
Now as we know that wave reaches to the shore which means energy start adding up to the molecules of shore
So here energy of molecules is increasing which directly shows that amplitude of wave is increasing so here we can say that due to increase in the amplitude of the wave the height of the wave is increasing and in terms of energy we can say that energy carried by the wave is converting into potential energy due to which height is increasing
