Why won't water wave undergo a phase change of pi when it propagates to a fixed wall just like a pulse of string does.

A phase change, also known as a state change, is a physical change in matter where a substance transitions from one state (solid, liquid, or gas) to another state.
A phase change can be caused by changes in temperature, pressure, or both. For example, increasing the temperature of a solid can cause it to melt into a liquid, and decreasing the pressure of a gas can cause it to condense into a liquid.
There are six main types of phase changes: melting, freezing, evaporation, condensation, sublimation, and deposition. Melting and freezing involve the transition between solid and liquid states, evaporation and condensation involve the transition between liquid and gas states, and sublimation and deposition involve the transition between solid and gas states.
A physical change involves a change in the physical properties of a substance, such as its state, shape, or size. A chemical change, on the other hand, involves a change in the chemical composition of a substance, resulting in the formation of new substances with different properties.
Yes, a substance can undergo multiple phase changes. For example, water can go from a solid (ice) to a liquid (water) to a gas (water vapor) as it is heated. It can also go from a gas (water vapor) to a liquid (water) to a solid (ice) as it is cooled.
