Once
started, the music swept along of its own momentum, carrying Bunny
with it. He was helpless. So was Robert and so was his mother. The
only opposition came from the room itself. What the green walls threw
back, the fire caught at and sent up the chimney. What the fire could
not reach, the ringed candelabrum turned nervously into
light, ring upon ring.
Sonic
waves are tridimensional waves that propagate from their source. Its
area would be the area of a sphere with radius R, where R is the
distance to the sonic source. According to Huygens Principle, each
obstacle that the waves face should become a secondary source of
spheric waves, similar to the ones described by William Maxwell in
this room. With the candelabrum, there is a more complicated
interaction between light and sonic waves.
