In the MIT video entitled “Breaking Glass with Sound [link]", the technician first had to match the (A) generated by the vibrating cone of the speaker to the (B) of the glass. As the speaker imparts (C) into the system, the glass molecules began to vibrate at higher and higher (D). This phenomenon is called (E). Eventually the glass shatters. If both the speaker and glass had instead been placed in a (F), the glass would never have broken since sound is a (G) wave.

In the Naval Academy’s video entitled “Making Standing Waves [link]” the waves in the wave tank form an interference pattern produced by two identical waves traveling through the same (A) but in (B) directions – the original waves and their reflections from the fixed wall. The name of this type of interference pattern is derived from the observation that the (C) appear motionless even though wave energy is constantly traveling from one end of the wave tank to the other end.
