A problem about wave

The two waves pass through each other without being disturbed. They will continue to move in their original directions. This is a result of the Law of Conservation of Energy.

Look at the animation given in the link below:

To start the animation, press the right most button [ > ] on the tool bar.

By the principle of superposition,they will cancel each other
Also,as there are kinetic energy before they bump together.By conservation of energy,the kinetic energy will change to internal energy

會抵消了，成一直線。能量可能會變成熱力。
