Light is a form of waves, photon waves, to be exact. They exist of actually two perpendicular waves in each other (allowing them to travel crazy distances without any extra energy). This kind of wave is called a transverse wave, or the typical up-down/cosine/sine waves, as shown in added picture in my next reply. When light waves hit a surface they are reflected from, they bounce back exactly reversed from their original wave pattern, creating the mirror effect.
Now, sound waves are another kind of wave called compression waves, which instead of going up and down go straight but compact into themselves and then shoot out where they compacted, kinda like if two people were holding hands and one person moved forward and pulled the other person and then the other person bumped into them and pushed them forward and so on. Now, what's important about these kinds of waves is the fact that due to their nature, when they are reversed they do not actually reverse. Their form just changes direction. That's why echoes aren't reversed.

Super sciency stuff!
Now, how exactly they do that is most likely much more sciency and unfortunately I don't know that, or else I would have invented the mirrors myself.
