Question:
Mirrors reflect light. Do they also reflect sound?



Replies:
Any acoustically smooth hard surface will reflect sound, so a glass mirror is a pretty good sound reflector but aluminized mylar is not. What constitutes an acoustically smooth and hard surface changes with the frequency of the sound.
