of 1D and 2D Standing Waves
Reflection/Transmission animations:
A pulse traveling from a region of
low wave speed to higher wave speed. The
reflected pulse is positive.
A pulse traveling from a region of
high wave speed to lower wave speed. The
reflected pulse is negative.
A pulse traveling along a string with
a fixed end. This is the limiting case
of when the second string is very heavy. The reflected pulse is negative.
