Reflection and rarefaction are both concepts related to the behavior of waves. Reflection occurs when a wave encounters a boundary and bounces back, changing direction. Rarefaction, on the other hand, is the region in a wave where particles are spread apart, causing a decrease in density. In summary, reflection involves a change in wave direction, while rarefaction involves a decrease in particle density within a wave.
Sound waves can undergo reflection, rarefaction, and compression phenomena. Reflection occurs when sound waves bounce off a surface. Rarefaction is the reduction of the density of air particles in the sound wave, while compression is the increase in density of air particles. Polarization, however, is a phenomenon typically associated with electromagnetic waves, not sound waves.
In a transverse wave, the peak and trough are like compression and rarefaction in a wave moving through a slinky. The peak is where the particles are closest together, similar to compression in a slinky, while the trough is where the particles are farthest apart, akin to rarefaction in a slinky.
An echo and a reflection are similar because they both involve the bouncing back of sound or light waves off a surface.
Rarefaction in sound refers to the decrease in air pressure caused by a sound wave, leading to the expansion of air molecules. Reflection in sound occurs when a sound wave strikes a surface and bounces back, creating an echo or reverberation effect.
Perhaps you are confusing with "refraction"? Refraction means that when a wave goes from one substance to another (for example, from air to water), it changes its direction. This is related with the index of refraction in the different substances, i.e., the wave has a different speed in the different substances.

compression and rarefaction
I believe you are referring to rarefaction. The "trough" of a compression / rarefaction wave is called rarefaction.
There are no perfect rhymes for the word rarefaction.

Both are transformations.

They are probably similar because they show a reflection of a person or an object.

Yes, they are the same.
